Applying basic techniques and concepts

Question 1

Explain properties of standard ABAP

Answer 1

• universal basic version
• unrestricted ABAP language
• covers entire ABAP scope
• access to all repo objects allowed except static package concept

Question 2

Explain properties of ABAP for key users

Answer 2

• intended for secure enhancement implementation
• restricted language set
• restricted access to repo objects

Question 3

Explain properties of ABAP for cloud development

Answer 3

• intended for development in the SAP BTP ABAP and S/4HANA Cloud ABAP environment
• restricted ABAP language set
• repo object access restricted

Question 4

What are the three sources of ABAP types

Answer 4

• ABAP built-it (numc, int, string, …)
• TYPE statement
• ABAP dictionary

Question 5

What is a constant

Answer 5

A constant is a data object with a hard-coded value that must not be changed during runtime.

Question 6

What is a literal

Answer 6

Literals are anonymous data objects with a hard-coded value. Literals are often used to define non-initial values for constants and non-initial starting values for variables.
There are three forms: number, text (type C) and string (Type string, in pair of backquotes “`”) literals

Question 7

What is the difference between string literals and string templates

Answer 7

string templates are placed within two “|”. They allow embedded expressions placed within curly brackets, which string literals do not:

|Total: { a + b } EUR|

DATA the_date TYPE d VALUE ‘19891130’.
|{ the_date DATE = ISO }| “=> ‘1989-11-30’,

Question 8

How do you join strings

Answer 8

Hello && World = HelloWorld
Hello && | | && World = Hello World

Question 9

How do you define a table type with a name and use it

Answer 9

TYPES <table_type_name> TYPE TABLE OF <row_type>.</row_type></table_type_name>

DATA <internal_table> TYPE <table_type_name>.</table_type_name></internal_table>

Question 10

What exceptions are catchable

Answer 10

All application- and many system exceptions

Question 11

What does sy-tabix and sy-index contain

Answer 11

sy-index is a iteration counter for do-enddo, tabix identifies the position of the currently processed table row in the current iteration

Question 12

How do you loop across a whole table

Answer 12

LOOP AT <internal-table> INTO <variable>. ENDLOOP.</variable></internal-table>

Question 13

What ways are there to interrupt a DO/ENDDO loop

Answer 13

1. Times: DO 5 TIMES. ENDDO.
2. IF: IF <cond>. EXIT. ENDIF. ENDDO.</cond>

Question 14

How do you catch exceptions

Answer 14

enclosing them in try/endtry statements containing catch blocks

Question 15

Explain the three special breakpoints

Answer 15

Statement Breakpoint: Stops program at specific ABAP statement. (e.g. whenever statement CLEAR is used)
Exception Breakpoint: Halts program when specific exception raised.
Conditional Breakpoints: Stops program based on condition.

Question 16

What is a watchpoint

Answer 16

Halts program when a specific variable is accessed or changed, enabling monitoring of its value. Access it by doubleclicking a variable in debug view and then rightclick in the table. Conditions can be added.

Question 17

When you press F8 (Continue) in the debugger, where could the program processing next stop?

Answer 17

at the end of the program, at a subsequent breakpoint

Question 18

which abap types are complete from C, D, P, I

Answer 18

I, D

Question 19

What is the work area of an internal table?

Answer 19

A variable with the same type as the row type of the internal table

Question 20

The IF condition IF a > 10. is followed by the ELSEIF condition ELSEIF a = 25.The variable a has the value 25. Which code branch or branches are executed?

Answer 20
