    1. Question 19. What Are Logical Databases? What Are The Advantages/ Dis-advantages Of Logical Databases? Answer :

      To read data from a database tables we use logical database. A logical database provides read-only access to a group of related tables to an ABAP/4 program.

      Advantages:

      • check functions which check that user input is complete, correct,and plausible.
      • Meaningful data selection.
      • central authorization checks for database accesses.
      • good read access performance while retaining the hierarchical data view determined by the application logic.

      dis advantages:

      • If you donot specify a logical database in the program attributes,the GET events never occur.
      • There is no ENDGET command,so the code block associated with an event ends with the next event statement (such as another GET or an END-OF-SELECTION).

Workbench objects like SAPscripts are client specific, some entries in customizing are client independent. If you display the object list for one change request, and then for each object the object attributes, you will find the flag client specific. If one object in the task list has this flag on, then that transport will be client dependent.

 

    1. Question 24. What Is The Difference Between Macro And Subroutine? Answer :

      Macros can only be used in the program the are defined in and only after the definition are expanded at compilation / generation. Subroutines (FORM) can be called from both the program the are defined in and other programs . A MACRO is more or less an abbreviation for some lines of code that are used more than once or twice. A FORM is a local subroutine (which can be called external). A FUNCTION is (more or less) a subroutine that is called external. Since debugging a MACRO is not really possible, prevent the use of them (I’ve never used them, but seen them in action). If the subroutine is used only local (called internal) use a FORM. If the subroutine is called external (used by more than one program) use a FUNCTION.

      Two types of LUW are:

      1. DB LUW – A database LUW is the mechanism used by the database to ensure that its data is always consistent. A database LUW is an inseparable sequence of database operations that ends with a database commit. The database LUW is either fully executed by the database system or not at all. Once a database LUW has been successfully executed, the database will be in a consistent state. If an error occurs within a database LUW, all of the database changes since the beginning of the database LUW are reversed. This leaves the database in the state it had before the transaction started.
      2. SAP LUW – A logical unit consisting of dialog steps, whose changes are written to the database in a single database LUW is called an SAP LUW. Unlike a database LUW, an SAP LUW can span several dialog steps, and be executed using a series of different work processes.

    1. Question 101. What Is The Difference Between Free And Refresh?Answer :

      Free – You can use FREE to initialize an internal table and release its memory space without first using the REFRESH or CLEAR statement. Like REFRESH, FREE works on the table body, not on the table work area. After a FREE statement, you can address the internal table again. It still occupies the amount of memory required for its header (currently 256 bytes). When you refill the table, the system has to allocate new memory space to the lines.

      Refresh – This always applies to the body of the table. As with the CLEAR statement, the memory used by the table before you initialized it remains allocated. To release the memory space, use the statement.

    1. Question 114. What Are Session Method And Call Transaction Method And Explain About Them?Answer :

      Session method – Use the BDC_OPEN_GROUP to create a session. Once we have created a session, then we can insert the batch input data into it with BDC_INSERT. Use the BDC_INSERT to add a transaction to a batch input session. We specify the transaction that is to be started in the call to BDC_INSERT. We must provide a BDCDATA structure that contains all the data required to process the transaction completely. Use the BDC_CLOSE_GROUP to close a session after we have inserted all of our batch input data into it. Once a session is closed, it can be processed.

      Call Transaction – In this method, we use CALL TRANSACTION USING to run an SAP transaction. External data does not have to be deposited in a session for later processing. Instead, the entire batch input process takes place inline in our program.

 

    1. Question 115. If You Have 10000 Records In Your File, Which Method You Use In Bdc?Answer :

      Call transaction is faster then session method. But usually we use session method in real time…because we can transfer large amount of data from internal table to database and if any errors in a session, then process will not complete until session get correct.

      In foreground jobs are only allowed a certain amount of runtime. Long running jobs usually times out in foreground, and have to be run background. Some customers has day-end jobs to fill custom tables, and these only run late at night, so they are scheduled as background jobs as well. There may be any of a hundred reasons why you want a job to run in background instead of foreground, and these are only 2 of them.

 

    1. Question 122. What Are Hashed Tables?Answer :

      Hashed tables – This is the most appropriate type for any table where the main operation is key access. You cannot access a hashed table using its index. The response time for key access remains constant, regardless of the number of table entries. Like database tables, hashed tables always have a unique key. Hashed tables are useful if you want to construct and use an internal table, which resembles a database table or for processing large amounts of data.
      SAMPLE PROG: THIS DOES NOTHING.
      REPORT Z_1 .
      TABLES: MARA.
      DATA: I TYPE HASHED TABLE OF MARA WITH UNIQUE KEY MATNR.

 

    1. Question 123. What Are Pooled Table?Answer :

      Table pools (pools) and table clusters (clusters) are special table types in the ABAP Dictionary. The data from several different tables can be stored together in a table pool or table cluster. Tables assigned to a table pool or table cluster are referred to as pooled tables or cluster tables.

      A table in the database in which all records from the pooled tables assigned to the table pool are stored corresponds to a table pool. The definition of a pool consists essentially of two key fields (Tabname and Varkey) and a long argument field (Vardata).

      Table Clusters Several logical data records from different cluster tables can be stored together in one physical record in a table cluster.

      A cluster key consists of a series of freely definable key fields and a field (Pageno) for distinguishing continuation records. A cluster also contains a long field (Vardata) that contains the contents of the data fields of the cluster tables for this key. If the data does not fit into the long field, continuation records are created. Control information on the structure of the data string is still written at the beginning of the Vardata field.

      Functional Areas – By creating functional areas, we can initially select this data. This ensures that the data is presented to the ABAP Query user in a meaningful way to accomplish the task, and that only the data that the user may use is presented.

      User Groups – A user group is a collection of users that work with about the same data and carry out similar tasks. The members of a user group can use all programs (queries) created by any user of the group. Changes to such a program are at once visible to all users. This ensures that all members of a user group use the same evaluation programs.

      ABAP Query– It consists of three components – queries, functional areas and user groups. The functional areas provide the user with an initial set of data in accordance with the task to be accomplished. All users must be members of at least one user group. All members of one user group can access the same data as well as the same program (queries) to create lists.

      – Using a report variant.
      – Using a range table.

 

    1. Question 271. What Is The Difference Between Leave Transaction And Call Transaction?Answer :

      In contrast to LEAVE TO TRANSACTION, the CALL TRANSACTION statement causes the system to start a new SAP LUW. This second SAP LUW runs parallel to the SAP LUW for the calling transaction.

 

    1. Question 272. What Are The Types Of Parameters In The Function Modules?Answer :

      In general, function module can have four types of parameters:
      – EXPORTING: for passing data to the called function.
      – IMPORTING: for receiving data returned from the function module.
      – TABLES: for passing internal tables only, by reference (that is, by address).
      – CHANGING: for passing parameters to and from the function.

 

    1. Question 273. What Are Function Modules?Answer :

      Function modules are general-purpose library routines that are available system-wide.

 

    1. Question 274. Does The External Program Run In The Same Sap Luw As The Caller, Or In A Separate One?Answer :

      – Transactions run with a separate SAP LUW.
      – Reports run with a separate SAP LUW.
      – Dialog modules run in the same SAP LUW as the caller.
      – Function modules run in the same SAP LUW as the caller.
      The only exceptions to the above rules are function modules called with IN UPDATE TASK (V2 function only) or IN BACKGROUND TASK (ALE applications). These always run in their own (separate) update transactions.

 

    1. Question 275. How Does The System Handle Roll Areas For External Program Components?Answer :

      – Transactions run in their own roll areas.
      – Reports run in their own roll areas.
      – Dialog modules run in their own roll areas.
      – Function modules run in the roll area of their callers.

 

    1. Question 276. What Is Roll Area?Answer :

      A roll area contains the program’s runtime context. In addition to the runtime stack and other structures, all local variables and any data known to the program are stored here.

    1. Question 286. What Is The Difference Between Synchronous And Asynchronous Updates?Answer :

      A program asks the system to perform a certain task, and then either waits or doesn’t wait for the task to finish. In synchronous processing, the program waits: control returns to the program only when the task has been completed. In asynchronous processing, the program does not wait: the system returns control after merely logging the request for execution.

 

    1. Question 287. What Are The Modes In Which Any Update Tasks Work?Answer :

      Synchronous and Asynchronous.

 

    1. Question 288. How The Transaction That Are Programmed By The User Can Be Protected?Answer :

      By implementing an authority check.

 

    1. Question 289. What Happens If We Use Leave To List-processing Without Using Suppress-dialog?Answer :

      If we don’t use Suppress-Dialog to next screen will be displayed but as empty, when the user presses ENTER, the standard list output is displayed.

 

    1. Question 290. How Is The Command Suppress-dialog Useful?Answer :

      Suppressing entire screens is possible using this command. This command allows us to perform screen processing “in the background”. The system carries out all PBO and PAI logic, but does not display the screen to the user. Suppressing screens is useful when we are branching to list-mode from a transaction dialog step.

 

    1. Question 291. When Will The Current Screen Processing Terminates?Answer :

      A current screen processing terminates when control reaches either a Leave-screen or the end of PAI.

 

    1. Question 292. What Is The Use Of The Statement Leave To List-processing?Answer :

      Leave to List-processing statement is used to produce a list from a module pool. Leave to list processing statement allows to switch from dialog-mode to list-mode within a dialog program.

 

    1. Question 293. What Are The Two Ways Of Producing A List Within A Transaction?Answer :

      By submitting a separate report.
      By using leave to list-processing.

 

    1. Question 294. Differentiate Between Static And Dynamic Step Loops?Answer :

      Step loops fall into two classes: Static and Dynamic. Static step loops have a fixed size that cannot be changed at runtime. Dynamic step loops are variable in size. If the user re-sizes the window the system automatically increases or decreases the number of step loop blocks displayed. In any given screen you can define any number of static step loops but only a single dynamic one.

 

    1. Question 295. How Can We Declare A Table Control In The Abap/4 Program?Answer :

      Using the syntax controls

      type tableview using screen .

 

    1. Question 296. Why Do We Need To Code A Loop Statement In Both The Pbo And Pai Events For Each Table In The Screen?Answer :

      We need to code a LOOP statement in both PBO and PAI events for each table in the screen. This is because the LOOP statement causes the screen fields to be copied back and forth between the ABAP/4 program and the screen field. For this reason, at least an empty LOOP….ENDLOOP must be there.

 

    1. Question 297. What Are The Dynapro Keywords?Answer :

      FIELD, MODULE, SELECT, VALUES and CHAIN are the dynapro keywords.

 

    1. Question 298. What Are The Differences Between Table Controls And Step Loops?Answer :

      TABLE CONTROLS are simply enhanced STEP LOOPS that display with the look and feel of a table widget in a desktop application. But from a programming standpoint, TABLE CONTROLS and STEP LOOPS are almost exactly the same. One major difference between STEP LOOPS and TABLE CONTROLS is in STEP LOOPS their table rows can span more than one time on the screen. By contrast the rows in a TABLE CONTROLS are always single lines, but can be very long. (Table control rows are scrollable). The structure of table control is different from step loops. A step loop, as a screen object, is simply a series of field rows that appear as a repeating block. A table control, as a screen object consists of:

      1. table fields (displayed in the screen).
      2. a control structure that governs the table display and what the user can do with it.

 

    1. Question 299. How Can We Use / Display Table In A Screen?Answer :

      ABAP/4 offers two mechanisms for displaying and using table data in a screen. These mechanisms are TABLE CONTROLS and STEP LOOPS.

 

    1. Question 300. What Are The Restrictions On Subscreens?Answer :

      Subscreens have several restrictions. They cannot:
      • Set their own GUI status
      • Have a named OK code
      • Call another screen
      • Contain an AT EXIT-COMMAND module
      • Support positioning of the cursor.

 

    1. Question 301. What Is A Screen Group? How It Is Useful?Answer :

      Screen group is a field in the Screen Attributes of a screen. Here we can define a string of up to four characters which is available at the screen runtime in the SY-DNGR field. Rather than maintaining field selection separately for each screen of a program, we can combine logically associated screens together in a screen group.

 

    1. Question 302. What Are The Attributes Of A Field That Can Be Activated Or Deactivated During Runtime?Answer :

      Input, Output, Mandatory, Active, Highlighted, Invisible.

 

    1. Question 303. Why Grouping Of Fields Is Required? What Is The Max No Of Modification Groups For Each Field?Answer :

      If the same attribute need to be changed for several fields at the same time these fields can be grouped together. We can specify up to four modification groups for each field.

 

    1. Question 304. What Is The Significance Of The Memory Table ‘screen’?Answer :

      At runtime, attributes for each screen field are stored in the memory table called ‘SCREEN’. We need not declare this table in our program. The system maintains the table for us internally and updates it with every screen change.

 

    1. Question 305. What Does The ‘suppress Dialog’ Do?Answer :

      Suppressing of entire screens is possible with this command. This command allows us to perform screen processing “in the background”. Suppresing screens is useful when we are branching to list-mode from a transaction dialog step.

 

    1. Question 306. What Is The Significance Of The Screen Number ‘0’?Answer :

      In “calling mode”, the special screen number 0 (LEAVE TO SCREEN 0) causes the system to jump back to the previous call level. That is, if you have called a screen sequence with CALL SCREEN leaving to screen 0 terminates the sequence and returns to the calling screen. If you have not called a screen sequence, LEAVE TO SCREEN 0 terminates the transaction.

 

    1. Question 307. What Happens If Only One Of The Commands Set Screen And Leave Screen Is Used Without Using The Other?Answer :

      If we use SET SCREEN without LEAVE SCREEN, the program finishes processing for the current screen before branching to . If we use LEAVE SCREEN without a SET SCREEN before it, the current screen process will be terminated and branch directly to the screen specified as the default next-screen in the screen attributes.

 

    1. Question 308. The Max Number Of Calling Modes Stacked At One Time Is?Answer :

      NINE.

 

    1. Question 309. What Is Dialog Module?Answer :

      A dialog Module is a callable sequence of screens that does not belong to a particular transaction.Dialog modules have their module pools , and can be called by any transaction.

 

    1. Question 310. The Field Sy-dynr Refers To?Answer :

      Number of the current screen.

 

    1. Question 311. The Syntex Used To Call A Screen As Dialog Box (pop Up) Is?Answer :

      CALL SCREEN .
      STARTING AT .
      ENDING AT .

 

    1. Question 312. Can We Specify The Next Screen Number With A Variable (*yes/no)?Answer :

      Yes.

 

    1. Question 313. What Is Difference Between Set Screen And Call Screen ?Answer :

      – With SET SCREEN the current screen simply specifies the next screen in the chain , control branches to this next screen as sonn as th e current screen has been processed .Return from next screen to current screen is not automatic .It does not interrupt processing of the current screen.If we want to branch to the next screen without finishing the current one, use LEAVE SCREEN.

      – With CALL SCREEN , the current (calling) chain is suspended , and a next screen (screen chain) is called .The called can then return to the suspended chain with the statement LEAVE SCREEN TO SCREEN 0 .Sometime we might want to let an user call a pop up screen from the main application screen to let him enter secondary information.After they have completed their enteries, the users should be able to close the popup and return directly to the place where they left off in the main screen.Here comes CALL SCREEN into picture .This statement lets us insert such a sequence intp the current one.

 

    1. Question 314. What Are The Different Message Types Available In The Abap/4 ?Answer :

      – There are 5 types of message types available.
      – E: ERROR.
      – W-WARNING.
      – I –INFORMATION.
      – A-ABNORMAL TERMINATION.
      – S-SUCCESS.

 

    1. Question 315. Which Function Type Has To Be Used For Using “at Exit-command” ?Answer :

      To Use AT EXIT – COMMAND ,We must assign a function Type “E” to the relevant function in the MENU Painter OR Screen Painter .

 

    1. Question 316. What Is An On “*-input Filed” Statement?Answer :

      ON *-INPUT
      – The ABAP/4 module is called if the user has entered the “*” in the first character of the field, and the field has the attribute *-entry in the screen Painter.You can use this option in Exceptionla cases where you want to check only fields with certain Kinds of Input.

 

    1. Question 317. What Is An “on Request Field” Statement?Answer :

      – ON REQUEST: The ABAP/4 Module is called only if the user has entered the value in the field value since the last screen display .The Value counts as changed Even if the User simply types in the value that was already there .In general ,the ON REQUEST condition is triggered through any Form of” MANUAL INPUT’.

 

    1. Question 318. What Is An “on Input Filed” Statements?Answer :

      – ON INPUT
      The ABAP/4 module is called only if a field contains the Value other than the initial Value.This initial Value is determined by the filed’s Dta Type: blanks for character Fields ,Zeroes for numerics. If the user changes the Fields Value back t o its initial value,ON INPUT does not trigger a call.

 

    1. Question 319. What Are The “field” And “chain” Statements?Answer :

      The FIELD and CHAIN flow logic statements let you Program Your own checks.FIELD and CHAIN tell the system Which fields you are checking and Whether the System should Perform Checks in the flow logic or call an ABAP/4 Module.

 

    1. Question 320. The Function Code Currently Active Is Ascertained By What Variable ?Answer :

      By SY-UCOMM Variable.

 

    1. Question 321. The Function Code Currently Active Is Ascertained By What Variable?Answer :

      The function code currently active in a Program can be ascertained from the SY-UCOMM Variable.

 

    1. Question 322. What Controls The Screen Flow?Answer :

      The SET SCREEN and LEAVE SCREEN statements controls screen flow.

 

    1. Question 323. How Are The Function Code Handles In Flow Logic?Answer :

      – When the User selects a function in a transaction ,the system copies the function code into a specially designated work field called OK_CODE.This field is Global in ABAP/4 Module Pool.The OK_CODE can then be evaluated in the corresponding PAI module. The function code is always passed in Exactly the same way , regardless of Whether it comes from a screen’s pushbutton,a menu option ,function key or other GUI element.

 

    1. Question 324. What Is To Be Defined For A Push Button Fields In The Screen Attributes?Answer :

      A function code has to be defined in the screen attributes for the push buttons in a screen.

 

    1. Question 325. How Does The Dialog Handle User Requests?Answer :

      when an action is performed ,the system triggers the PROCESS AFTER INPUT event.The data passed includes field screen data data entered by the user and a function code. A functioncode is a technical name that has been allocated in a screen Painter or Menu Painter to a meny entry,a push button,the ENTER key or a function Key of a screen.An internal work field(ok-code)in the PAI module evaluates the function code,and the appropriate action is taken.

 

    1. Question 326. How Does The Interection Between The Dynpro And The Abap/4 Modules Takes Place?Answer :

      A transaction is a collection os screens and ABAP/4 routines, controlled and executed by a Dialog processor. The Dilaog processor processes screen after the screen, thereby triggering the appropriate ABAP/4 processing of each screen. For each screen, the system executes the flow logic that contains the corresponding ABAP/4 processing. The controls passes from screen flow logic to ABAP/4 code and back.

 

    1. Question 327. What Is Gui Status? How To Create /edit Gui Status?Answer :

      A GUI status is a subset of the interface elements used for a certain screen.The status comprises those elements that are currently needed by the transaction .The GUI status for a transaction may be composed of the following elements:
      -Title bar.
      -Mneu bar.
      -Application tool bar
      -Push buttons.
      To create and edit GUI status and GUI title,we use the Menu Painter.

 

    1. Question 328. Can We Use Flow Logic Control Key Words In Abap/4 And Vice-versa?Answer :

      The flow control of a dynpro consists os a few statements that syntactically ressemble ABAP/4 statements. However, We cannot use flow control keywords in ABAP/4 and vice-versa.

 

    1. Question 329. Can We Use Write Statements In Screen Fields?if Not How Is Data Transferred From Field Data To Screen Fields?Answer :

      We cannot write field data to the screen using the WRITE statement.The system instead transfers data by comparing screen fields names with ABAP/4 variable names.If both names are the same,it transfers screen fields values to ABAP/4 programs fields and Vice Versa.This happens immediately after displaying the screen.

 

    1. Question 330. What Is A Abap/4 Module Pool?Answer :

      Each dynpro refers to exactly one ABAP/4 dialog program.Such a dialog program is also called a module pool ,since it consists on interactive modules.

 

    1. Question 331. What Is Dynpro? What Are Its Components?Answer :

      A dynpro (Dynamic Program) consists of a screen and its flow logic and controls exactly one dialog steps.
      – The different components of the dynpro are :

      • Flow Logic– calls of the ABAP/4 modules for a screen .
      • Screen layout- Positions of the text ,fields,pushbuttons and so on for a screen.
      • Screen Attributes- Number of the screen,number of the subsequent screen,and others.
      • Fields attributes– Definition of the attributes of the individual fields on a screen.

 

    1. Question 332. What Is Pbo And Pai Events?Answer :

      PBO- Process Before Output-It determines the flow logic before displaying the screen.
      PAI-Process After Input-It determines the flowlogic after the display of the screen and after receiving inputs from the User.

 

    1. Question 333. What Are The Requirements A Dialog Program Must Fulfill?Answer :

      A dialog program must fulfil the following requirements:
      – a user friendly user interface.
      – Format and consistancey checks for the data entered by the user.
      – Easy correction of input errors.
      – Access to data by storing it in the data bases.

 

    1. Question 334. What Is A Transaction?Answer :

      A transaction is dialog program that change data objects in a consistant way.

 

    1. Question 335. How Many Lists Can A Program Can Produce?Answer :

      Each program can produce up to 21 lists: one basic list and 20 secondary lists. If the user creates a list on the next level (that is, SY-LSIND increases), the system stores the previous list and displays the new one. Only one list is active, and that is always the most recently created list.

 

    1. Question 336. What Will Exactly The Hide Statement Do?Answer :

      For displaying the details on secondary lists requires that you have previously stored the contents of the selected line from within the program. To do this, ABAP/4 provides the HIDE statement. This statement stores the current field contents for the current list line. When calling a secondary list from a list line for which the HIDE fields are stored, the system fills the stored values back into the variables in the program. In the program code, insert the HIDE statement directly after the WRITE statement for the current line. Interactive lists provide the user with the so-called ‘INTERACTIVE REPORTIN’ facility. For background processing the only possible method of picking the relevant data is through ‘NON INTERACTIVE REPORT’ . After starting a background job, there is no way of influencing the program. But whereas for dialog sessions there are no such restrictions.

 

    1. Question 337. How Can You Manipulate The Presentation And Attributes Of Interactive Lists?Answer :

      -Scrolling through Interactive Lists.
      -Setting the Cursor from within the Program.
      -Modifying List Lines.

 

    1. Question 338. How To Pass Data From List To Report?Answer :

      ABAP/4 provides three ways of passing data:
      -Passing data automatically using system fields.
      -Using statements in the program to fetch data.
      -Passing list attributes.

 

    1. Question 339. How The At-user Command Serves Mainly In Lists?Answer :

      The AT USER-COMMAND event serves mainly to handle own function codes. In this case, you should create an individual interface with the Menu Painter and define such function codes.

 

    1. Question 340. When The Get Cursor Command Used In Interactive Lists?Answer :

      If the hidden information is not sufficient to uniquely identify the selected line, the command GET CURSOR is used. The GET CURSOR command returns the name of the field at the cursor position in a field specified after the addition field, and the value of the selected field in a field specified after value.

 

    1. Question 341. What Is Meant By Hide Area?Answer :

      The hide command temporarily stores the contents of the field at the current line in a system-controlled memory called the HIDE AREA. At an interactive event, the contents of the field are restored from the HIDE AREA.

 

    1. Question 342. Can We Display A List In A Pop-up Screen Other Than Full-size Stacked List?Answer :

      Yes, we can display a list in a pop-up screen using the command WINDOW with the additions starting at X1 Y1 and ending at X2 Y2 to set the upper-left and the lower-right corners where x1 y1 and x2 y2 are the coordinates.

 

    1. Question 343. In Which System Field Does The Name Of Current Gui Status Is There?Answer :

      The name of the current GUI STATUS is available in the system field SY-PFKEY.

 

    1. Question 344. Can We Create A Gui Status In A Program From The Object Browser?Answer :

      Yes. You can create a GUI STATUS in a program using SET PF-STATUS.

 

    1. Question 345. What Is The Length Of Function Code At User-command?Answer :

      Each menu function, push button, or function key has an associated function code of length FOUR (for example, FREE), which is available in the system field SYUCOMM after the user action.

 

    1. Question 346. What Is Meant By Hotspots?Answer :

      A Hotspot is a list area where the mouse pointer appears as an upright hand symbol. When a user points to that area (and the hand cursor is active), a single click does the same thing as a double-click. Hotspots are supported from R/3 release 3.0c.

 

    1. Question 347. Is The Basic List Deleted When The New List Is Created?Answer :

      No. It is not deleted and you can return back to it using one of the standard navigation functions like clicking on the back button or the cancel button.

 

    1. Question 348. What Is Meant By Stacked List?Answer :

      A stacked list is nothing but secondary list and is displayed on a full-size screen unless you have specified its coordinates using the window command.

 

    1. Question 349. What Are The Drill-down Features Provided By Abap/4 In Interactive Lists?Answer :

      ABAP/4 provides some interactive events on lists such as AT LINE-SELECTION (double click) or AT USER-COMMAND (pressing a button). You can use these events to move through layers of information about individual items in a list.

 

    1. Question 350. What Are The User Interfaces Of Interactive Lists?Answer :

      If you want the user to communicate with the system during list display, the list must be interactive. You can define specific interactive possibilities in the status of the list’s user interface (GUI). To define the statuses of interfaces in the R/3 system, use the Menu Painter tool. In the Menu Painter, assign function codes to certain interactive functions. After an user action occurs on the completed interface, the ABAP/4 processor checks the function code and, if valid, triggers the corresponding event.

 

    1. Question 351. What Are The Types Of Messages?Answer :

      A message can have five different types. These message types have the following effects during list processing:

      • A (=Abend):
      • E (=Error) or W (=Warning):
      • I (=Information):
      • S (=Success):

 

    1. Question 352. How To Maintain Lists?Answer :

      To return from a high list level to the next-lower level (SY-LSIND), the user chooses Back on a secondary list. The system then releases the currently displayed list and activates the list created one step earlier. The system deletes the contents of the released list. To explicitly specify the list level, into which you want to place output, set the SY-lsind field. The system accepts only index values, which correspond to existing list levels. It then deletes all existing list levels whose index is greater or equal to the index specify. For example, if you set SY-LSIND to 0, the system deletes all secondary lists and overwrites the basic list with the current secondary list.

 

    1. Question 353. Can We Call Reports And Transactions From Interactive Reporting Lists?Answer :

      Yes. It also allows you to call transactions or other reports from lists. These programs then use values displayed in the list as input values. The user can, for example, call a transaction from within a list of change the database table whose data is displayed in the list.

 

    1. Question 354. What Is Interactive Reporting?Answer :

      A classical non-interactive report consists of one program that creates a single list. Instead of one extensive and detailed list, with interactive reporting you create basic list from which the user can call detailed information by positioning the cursor and entering commands. Interactive reporting thus reduces information retrieval to the data actually required.

 

    1. Question 355. How To Create User Interfaces For Lists?Answer :

      The R/3 system automatically, generates a graphical user interface (GUI) for your lists that offers the basic functions for list processing, such as saving or printing the list. If you want to include additional functionality, such as pushbuttons, you must define your own interface status. To create a new status, the Development Workbench offers the Menu Painter. With the Menu Painter, you can create menus and application toolbars. And you can assign Function Keys to certain functions. At the beginning of the statement block of AT END-OF-SELECTION, active the status of the basic list using the statement: SET PF-STATUS ‘STATUS’.

 

    1. Question 356. How To Select Valid Lines For Secondary List?Answer :

      To prevent the user from selecting invalid lines, ABAP/4 offers several possibilities. At the end of the processing block END-OF-SELECTION, delete the contents of one or more fields you previously stored for valid lines using the HIDE statement. At the event AT LINE-SELECTION, check whether the work area is initial or whether the HIDE statement stored field contents there. After processing the secondary list, clear the work area again. This prevents the user from trying to create further secondary lists from the secondary list displayed.

 

    1. Question 357. What Is Secondary List?Answer :

      It allows you to enhance the information presented in the basic list. The user can, for example, select a line of the basic list for which he wants to see more detailed information. You display these details on a secondary list. Secondary lists may either overlay the basic list completely or you can display them in an extra window on the screen. The secondary lists can themselves be interactive again.

      Yes. But it leads to unnecessary data redundancy.

 

    1. Question 367. What Is The Difference Between Internal Tables And Extract Datasets?Answer :

      • The lines of an internal table always have the same structure. By using extract datasets, you can handle groups of data with different structure and get statistical figures from the grouped data.
      • You have to define the structure of the internal table at the beginning. You need not define the structure of the extract dataset.
      • In contrast to internal tables, the system partly compresses exact datasets when storing them. This reduces the storage space required.
      • Internal tables require special work area for interface whereas extract datasets do not need a special work area for interface.

 

    1. Question 368. What Happens If A Function Module Runs In An Update Task?Answer :

    1. Question 371. What Is A Function Group?Answer :

      A function group is a collection of logically related modules that share global data with each other. All the modules in the group are included in the same main program. When an ABAP/4 program contains a CALL FUNCTION statement, the system loads the entire function group in with the program code at runtime. Every function module belongs to a function group.

 

    1. Question 372. What Is The Difference Between The Function Module And A Normal Abap/4 Subroutine?Answer :

      In contrast to normal subroutines function modules have uniquely defined interface. Declaring data as common parts is not possible for function modules. Function modules are stored in a central library.

 

    1. Question 373. How Can One Distinguish Between Different Kinds Of Parameters?Answer :

      • Input parameters are used to pass data to subroutines.
      • Output parameters are used to pass data from subroutines.

 

    1. Question 374. What Are The Different Methods Of Passing Data?Answer :
      • Calling by reference– During a subroutine call, only the address of the actual parameter is transferred to the formal parameters. The formal parameter has no memory of its own, and we work with the field of the calling program within the subroutine. If we change the formal parameter, the field contents in the calling program also changes.
      • Calling by value– During a subroutine call, the formal parameters are created as copies of the actual parameters. The formal parameters have memory of their own. Changes to the formal parameters have no effect on the actual parameters.
      • Calling by value and result- During a subroutine call, the formal parameters are created as copies of the actual parameters. The formal parameters have their own memory space. Changes to the formal parameters are copied to the actual parameters at the end of the subroutine.

 

    1. Question 375. What Are The Different Types Of Parameters?Answer :

      Formal Parameters– Parameters, which are defined during the definition of subroutine with the FORM statement.
      Actual Parameters– Parameters which are specified during the call of a subroutine with the PERFORM statement.

 

    1. Question 376. What Are The Types Of Subroutines?Answer :
      • Internal Subroutines– The source code of the internal subroutines will be in the same ABAP/4 program as the calling procedure (internal call).
      •  External Subroutines– The source code of the external subroutines will be in an ABAP/4 program other than the calling procedure.

 

    1. Question 377. What Are Subroutines?Answer :

      Subroutines are program modules, which can be called from other ABAP/4 programs or within the same program.

 

    1. Question 378. Is It Possible To Pass Data To And From Include Programs Explicitly?Answer :
