CONTROL STATEMENTS.

Control Break Statements

Control break statements are used to create statement blocks which process only specific table lines the LOOP – ENDLOOP block.

You open such a statement block with the control level statement AT and close it with the control level statement ENDAT. The syntax is as follows:

Table should be sorted when you use control-break statements

You can break the sequential access of internal tables by using these statements.

Syntax:

At first.

Endat.

This is the first statement to get executed inside the loop (remember control break statements are applicable only inside the loop)

So in this block you can write or process those statements which you want to get executed when the loop starts.

At New carrid.

Write:/ carrid.

Endat.

In this case whenever the new carrid is reached, carrid will be written.

At End of carrid.

Uline.

Endat.

In this case whenever the end of carrid is reached, a line will be drawn.

At Last.

Write:/ ‘Last Record is reached’.

Endat.

Processing of statements within this block is done when entire processing of entire internal table is over. Usually used to display grand totals.

You can use either all or one of the above control break statements with in the loop for processing internal table.

At end of carrid.

Sum.

Endat.

In above case the statement SUM (applicable only within AT-ENDAT) will sum up all the numeric fields in internal table and result is stored in same internal table variable.

All this AT NEW, AT FIRST, AT END OF and AT LAST are called control break statements of Internal tables and are used to calculate the TOTALS based on sertain key fields in that internal table

FIrst to use these statements the ITAB has to be sorted by the key fields on whcih you need the SUM of the fields.

Some time you will get * when mopving data from this int table to other table using these commands

so you have to use

READ TABLE ITAB INDEX SY-TABIX in AT..ENDAT..if you are using other fields between them

DATA: sflight_tab TYPE SORTED TABLE OF sflight

WITH UNIQUE KEY carrid connid fldate,

sflight_wa LIKE LINE OF sflight_tab.

SELECT *

FROM sflight

INTO TABLE sflight_tab.

LOOP AT sflight_tab INTO sflight_wa.

AT NEW connid.

WRITE: / sflight_wa-carrid,

sflight_wa-connid.

ULINE.

ENDAT.

WRITE: / sflight_wa-fldate,

sflight_wa-seatsocc.

AT END OF connid.

SUM.

ULINE.

WRITE: / 'Sum',

sflight_wa-seatsocc UNDER sflight_wa-seatsocc.

SKIP.

ENDAT.

AT END OF carrid.

SUM.

ULINE.

WRITE: / 'Carrier Sum',

sflight_wa-seatsocc UNDER sflight_wa-seatsocc.

NEW-PAGE.

ENDAT.

AT LAST.

SUM.

WRITE: / 'Overall Sum',

sflight_wa-seatsocc UNDER sflight_wa-seatsocc.

ENDAT.

ENDLOOP.
