ABAP Programming Fundamentals: Key Concepts Q&A

ABAP Fundamentals: Key Concepts and Technical Q&A

Review essential knowledge points covering ABAP syntax, data structures, system fields, and event processing.

1. Client Dependency in ABAP Dictionary Tables

   If a table does not have MANDT as part of the primary key, it is:

   Client-independent

2. Invalid ABAP CALL Statement

   In regard to CALL, which of the following is NOT a valid statement?

   CALL PROGRAM

3. Characteristics of Transparent Tables

   Name the type of ABAP Dictionary table that has these characteristics:

   • Same number of fields as the database table
   • Same name as the database table
   • Maps 1:1 to the database table

   Transparent Table

4. ABAP Event Structure

   An event starts with an event keyword and ends with:

   Another event keyword

5. System Field for Current Date

   What is the system field for the current date?

   SY-DATUM

6. Understanding APPENDING TABLE Clause

   The following code indicates:

   SELECT fld1 fld2 FROM tab1 APPENDING TABLE itab WHERE fld1 IN sfld1.

   Add rows to the existing rows of itab.

7. Modifying ABAP Constants

   You may change the following data object as shown below so that it equals 3.14:

   CONSTANTS: PI TYPE P DECIMALS 2 VALUE '3.1'. PI = '3.14'.

   FALSE (Constants cannot be changed.)

8. SAP Locking Service for Data Integrity

   The SAP service that ensures data integrity by handling locking is called:

   Enqueue/Dequeue

9. The GET LATE Event Description

   Which of these sentences most accurately describes the GET VBAK LATE event?

   This event is processed after all occurrences of the GET VBAK event are completed.

10. Hashed Internal Table Performance

    Which of the following is not a true statement regarding a hashed internal table type?

    Response time for accessing a row depends on the number of entries in the table. (Hashed tables offer near-constant access time.)

11. Database-Specific SQL in ABAP

    To include database-specific SQL statements within an ABAP program, code them between:

    EXEC SQL and ENDEXEC

12. Measuring Code Execution Time

    To measure how long a block of code runs, use the ABAP statement:

    GET RUN TIME FIELD

13. Obsolete Internal Table Declaration

    Given the declaration: DATA: BEGIN OF itab OCCURS 10,

    This will result in: None of the above. (This syntax is obsolete and defines a header line.)

14. SY-TFILL After DESCRIBE TABLE

    After a DESCRIBE TABLE statement, SY-TFILL will contain:

    The number of rows in the internal table.

15. Declaring Custom Internal Table Types

    You may declare your own internal table type using the TYPES keyword.

    TRUE

16. Mixing COLLECT and APPEND

    After adding rows to an internal table with COLLECT, you should avoid adding more rows with APPEND.

    TRUE

17. Control Break Processing Components

    Which of the following is not a component of control break processing when looping at an internal table?

    AT START OF (Note: This answer is likely intended to be an incorrect option from a list, as AT START OF is a valid control break event.)

18. Using the TABLES Statement

    A dictionary table is made available for use within an ABAP program via the TABLES statement.

    FALSE (The TABLES statement is obsolete.)

19. Hiding Selection Criteria

    Which statement would be best for hiding further selection criteria until a function is chosen?

    CALL SELECTION-SCREEN

20. Flow Logic Condition for Non-Initial Values

    What must you code in the flow logic to prevent a module from being called unless a field contains a non-initial value?

    ON INPUT

21. Triggering AT USER-COMMAND

    The AT USER-COMMAND event is triggered by functions defined in the:

    Menu Painter Status
