What is control break statements?
Control Break Statements are used to control the sequential execution of the statements inside loop and end loop. This can be achieved by using the break statements and it is applicable only inside the loop and End loop.
How do you break a loop in SAP ABAP?
- EXIT – loop.
- Syntax.
- EXIT.
- Effect.
- If the EXIT statement is specified within a loop, it exits the loop by ending the current loop pass. The program flow resumes after the closing statement in the loop.
- Note.
- Outside of a loop, the statement EXIT exits the current processing block (see EXIT – Processing Block).
- Example.
What is the use of loop statement in SAP ABAP?
A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages. ABAP programming language provides the following types of loop to handle looping requirements.
What are prerequisites for writing control break statements?
The prerequisite for using control break statements is that the internal table must be sorted in the exact order of the components of its row type according to the processing sequence in which the LOOP loop reads the rows of the internal table.
What is at first in SAP ABAP?
->at the end of the internal table (at end, at last). AT FIRST: To display the required data at the beginning of the internal table.
What is difference between BAPI and RFC?
BAPI are RFC enabled function modules. The difference between RFC and BAPI are business objects. While RFC are immediate system call, Some BAPIs provide essential functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types.
What are modularization techniques in ABAP?
All ABAP programs are modular in structure and made up of processing blocks (see Structure of Processing Logic ). There are two kinds of processing blocks, those that are called from outside a program by the ABAP runtime system, and those that can be called by ABAP statements in ABAP programs.
What is Sy-Tabix in SAP ABAP?
Sy-tabix is used to find the current line in the internal table; it’s a current line index. Whereas sy-index in used to find the number of current pass in the loop statement.
What is lock object in ABAP?
Lock Object is a feature offered by ABAP Dictionary that is used to synchronize access to the same data by more than one program. Lock objects are used in SAP to avoid the inconsistency when data is inserted into or changed in the database.
What is internal table in ABAP?
Internal tables provide a means of taking data from a fixed structure and storing it in working memory in ABAP. The data is stored line by line in memory, and each line has the same structure. A particularly important use for internal tables is for storing and formatting data from a database table within a program.
What is difference between on change of and at new field?
AT NEW statement triggers when concerned field changes and also when the fields left to the concerned field changes,in this case if f1 or f2 changes to a new value. ON CHANGE OF statement triggers ony if the concerned field changes, in this case f2.
How to use control break statements in looping?
The prerequisite for using control break statements is that the internal table must be sorted in the exact order of the components of its row type according to the processing sequence in which the LOOP loop reads the rows of the internal table. The control break “ON CHANGE OF – ENDON”, can be used in any loop, not just LOOP… ENDLOOP.
How to break the normal flow of an ABAP loop?
If you want to break the normal flow of an ABAP loop, then you need Control Break Statements in ABAP Loop. ABAP provide three loop control statements i.e. CONTINUE, CHECK, EXIT. This statement will pass the current loop unconditionally. It needs IF statements to apply condition.

ABAP provide three loop control statements i.e. CONTINUE, CHECK, EXIT. This statement will pass the current loop unconditionally. It needs IF statements to apply condition.
What is the use of control break processing?
Control break processing is used to execute a piece of code whenever a specific condition in the data is detected during the processing of internal table loop. The following control break statements are available with in LOOP and ENDLOOP.
