Ans Each field of cluster table behaves as tables, which contains the number of entries.

217) What are client dependant objects in ABAP / SAP?
Ans SAP Script layout, text element, and some DDIC objects.

218) On which event we can validate the input fields in module programs?
Ans In PAI (Write field statement on field you want to validate, if you want to validate group of fields put in chain and End chain statement.)

219) In selection screen, I have three fields, plant material number and material group. If I input plant how do I get the material number and material group based on plant dynamically?
Ans AT SELECTION-SCREEN ON VALUE-REQUEST FOR MATERIAL.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
to get material and material group for the plant.

220) How do you get output from IDOC?
Ans Data in IDOC is stored in segments; the output from IDOC is obtained by reading the data stored in its respective segments.


221) When top of the page event is triggered?
Ans After executing first write statement in start-of-selection event.

222) Can we create field without data element and how?
Ans In SE11, one option is available above the fields strip i.e. Data element / direct type.

223) Fields of VBAK Table.
Ans VBAK – Sales Document : Header Data

Details about Sales Organization, Distribution Channel, Division, Sales Group, Sales Office, Business Area, Outline Agreements, etc

224) Which transaction code can I used to analyze the performance of ABAP program.
Ans Transaction Code AL21.

225) How can I copy a standard table to make my own Z_TABLE?
Ans Go to transaction SE11. Then there is one option to copy table. Press that button. Enter the name of the standard table and in the Target table enter Z_table name and press enter.

226) What is runtime analysis? Have you used this?
Ans It checks program execution time in microseconds. When you go to SE30. If you give desired program name in performance file. It will take you to below screen. You can get how much fast is your program.

227) What is meant by performance analysis?
Ans




228) How to transfer the objects? Have you transferred any objects?
Ans



229) How did you test the developed objects?
Ans There are two types of testing
- Negative testing
- Positive testing

In negative testing, we will give negative data in input and we check any errors occurs.
In positive testing, we will give positive data in input for checking errors.

230) How did you handle errors in Call Transaction?
Ans We can create an internal table like 'bsgmcgcoll'. All the messages will go to internal table. We can get errors in this internal table.

Below messages are go to internal table. When you run the call transaction.

1) TCODE
2) Message Type
3) Message Id
4) Message Number
5) MSGV1
6) MSGV2
7) MSGV3
8) MSGV4

CALL TRANSACTION TCODE USING BDCDATA MODE A/N/E.

UPDATE MODE A/S MESSAGE INTO BDCDATA.

THEN PUT LOOP…ENDLOOP OF BDCMSGCOLL
CALL FUNCTION ‘FORMAT_WRITE’

EXPORT = SYSTEM FIELD
IMPORT = MSG TEXT ERROR

231) Among the Call Transaction and Session Method, which is faster?
Ans 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.

232) What are the difference between Interactive and Drill Down Reports?
Ans 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.

Drill down report is nothing but interactive report...drilldown means above paragraph only.

233) How to pass the variables to forms?
Ans




234) What is the table, which contain the details of all the name of the programs and forms?
Ans Table contains vertical and horizontal lines. We can store the data in table as blocks. We can scroll depends upon your wish. And these all are stored in database (data dictionary).

235) What are Standard Texts?
Ans




236) What is the difference between Clustered Tables and Pooled Tables?
Ans A pooled table is used to combine several logical tables in the ABAP/4 dictionary. Pooled tables are logical tables that must be assigned to a table pool when they are defined.

Cluster table are logical tables that must be assigned to a table cluster when they are defined. Cluster table can be used to store control data. They can also used to store temporary data or text such as documentation.

237) What is PF-STATUS?
Ans PF-Status is used in interactive report for enhancing the functionality. If we go to SE41, we can get menus, items and different function keys, which we are using for secondary list in interactive report.




238) Among "Move" and "Move Corresponding", which is efficient one?
Ans I guess, 'move corresponding' is very efficient then 'move' statement. Because usually we use this statement for internal table fields only...so if we give move corresponding. Those fields only moving to other place (what ever you want).

239) What are the Output Type, Transaction codes, Page Format?
Ans




240) Where we use Chain and End chain?
Ans In Screen Programming

241) Do you use select statement in loop…end loop, how will be the performance? To improve the performance?
Ans




242) In select-options, how to get the default values as current month first date and last date by default? Eg: 1/12/2004 and 31/12/2004
Ans




243) What are IDOCs?
Ans IDOCs are intermediate documents to hold the messages as a container.

244) What are screen painter? Menu painter? Gui status? ..etc.
Ans dynpro - flow logic + screens.

menu painter -

GUI Status - It is subset of the interface elements (title bar, menu bar, standard tool bar, push buttons) used for a certain screen.

The status comprises those elements that are currently needed by the transaction.

245) What is screen flow logic? What are the sections in it? Explain PAI and PBO.
Ans The control statements that control the screen flow.

PBO - This event is triggered before the screen is displayed.
PAI - This event is responsible for processing of screen after the user enters the data and clicks the pushbutton.

246) Overall how do you write transaction programs in SAP?
Ans Create program-SE93-create transaction code -Run it from command field.

Create the transaction using object browser (SE80)
Define the objects e.g. screen, Transactions. – Modules – PBO, PAI.

247) Does SAP has a GUI screen painter or not? If yes what operating systems is it available on? What is the other type of screen painter called?
Ans Yes.

Operating System – Windows based
Screen Painter – Alpha numeric Screen Painter


248) What are step loops? How do you program page down page up in step loops?
Ans Step loops are repeated blocks of field in a screen.

Step loops: Method of displaying a set of records.
Page down & Page up: decrement / increment base counter
Index = base + sy-step1 – 1

249) Is ABAP a GUI language?
Ans Yes, ABAP IS AN EVENT DRIVEN LANGUAGE.

250) Normally how many and what files get created when a transaction program is written?
What is the XXXXXTOP program?
Ans Main program with A Includes

1. TOP INCLUDE – GLOBAL DATA
2. Include for PBO
3. Include for PAI
4. Include for Forms

251) What are the include programs?
Ans When the same sequence of statements in several programs is to be written repeatedly. They are coded in include programs (External programs) and are included in ABAP/4 programs.

252) Can you call a subroutine of one program from another program?
Ans Yes, only external subroutines Using 'SUBMIT' statement.

253) What are user exits? What is involved in writing them? What precautions are needed?
Ans User defined functionality included to predefined SAP standards. Point in an SAP program where a customer's own program can be called. In contrast to customer exits, user exits allow developers to access and modify program components and data objects in the standard system. On upgrade, each user exit must be checked to ensure that it conforms to the standard system.

There are two types of user exit:

1. User exits that use INCLUDEs - These are customer enhancements that are called directly in the program.
2. User exits that use TABLEs - These are used and managed using Customizing. Should find the customer enhancements belonging to particular development class.
254) What are RFCs? How do you write RFCs on SAP side?
Ans




255) What are the general naming conventions of ABAP programs?
Ans Should start with Y or Z.
