Answer / niranjan

The Control Break Statements are used to print headings,subheadings,totals and subtotal.
We must use this statements inside the loop.

1.AT FIRST...........ENDAT:It is useful to print headings.
-->it will triggered before starting a first record in a loop.

2.AT LAST............ENDAT:It is useful to print TOTALS.
-->it will triggered after the last record in a loop.

3.AT NEW ON..........ENDAT:It is useful to print subheadings.
-->it will triggered before starting a new value for that particular field.

4.AT END OF..........ENDAT:It is useful to display sub-totals.
-->it will triggered after heading the old value.

5.ON CHANGE OF.......ENDAT:It is same as 'AT FIRST' but the only difference is we can use 'ON CHANGE OF' in any kind of loop statements like loop.....endloop,select.....endselect,do.....enddo,while.....endwhile.
-->it will triggered before starting a new value.

Answer / arasu

Control Break Statement is different from Control statement,
the BREAK, EXIT, CONTINUE are used to break and come out of
the current loop where it occurs, where as AT NEW, AT END,
AT LAST, AT FIRST is used to check for a table field value
(internal table). When u asked for control statements alone,
u need to answer as BREAK, EXIT, CONTINUE, CHECK because it
controls the program flow.

Answer / kotireddy5

Control break statements:

Control break statements are like events inside the loop. There are 5 control break statements in ABAP. These are used within loop.(Except ON CHANGE OF which can be used outside the loop as well)


• AT FIRST - ENDAT
• AT NEW - ENDAT
• AT END OF - ENDAT
• AT LAST - ENDAT
• ON CHANGE OF


Explanation:

AT FIRST : Will trigger at the first run of the loop.

AT LAST: Will trigger at the last run of the loop.

The below 3 events are normally used when the table is sorted.


AT END OF : When we use At end for a field, it will trigger whenever there is any change in any of the fields from the left to that of the particular field. The trigger point will be the at the last occurrence of the same value for the field.

AT NEW: When we use At new for a field, it will trigger whenever there is any change in any of the fields from the left to that of the particular field.The trigger point will be the at the first occurrence of the new value for the field.

ON CHANGE OF: On change of it triggers only when there is any change in the particular field.
On change of can be used outside the loop too


Example Program:

Here is an example program which gives you the practical understanding of all control break statements.

Example Program for Control Break Statements
NOTE: It is important to note that we need a temporary work-area apart from the work-area used in loop for the last 3 control break statements. If we directly use the work-area of the loop, then we will get **** value and not the output we are expecting.

Answer / rv karthikeyan

Hi this is karthikeyan


control break statement: It is used to control the data flow inside the loop,for example if we need to add some functionality at run time for example subtotal for every new value triggered or sub heading,we use control break statement,now we see the types of control break statement.

at first: when the loop start first this at first will trigger,that when the loop starts the control goes to the at first statement and executed all the function inside it.

at new: when the first occurrence of the new value found this at new will trigger,used for the sub heading or page break purpose.

at end: when the last occurrence of the new value found this at end will trigger,used mainly for sub total purpose.

at last: when the last record in the loop over this at last will trigger used for grand total purpose.

Hope u got idea...

RV Karthikeyan.
