Hi Chandra,

Is it on change of??? i don't on change-request any where

REPORT ABC.

DATA : BEGIN OF ITAB OCCURS 0,

bukrs like t001-bukrs,

f1(10) type c,

end of itab.

itab-bukrs = '1000'.

itab-f1 = '1111111'.

append itab.

itab-bukrs = '1100'.

itab-f1 = '3333333'.

append itab.

itab-bukrs = '1200'.

itab-f1 = '555555'.

append itab.

*----

AT NEW

loop at itab.

at new bukrs.

write 😕 itab-bukrs , itab-f1.

endat.

endloop.

*----

AT ONCHANGE

Hi,

ON CHANGE OF has become obsolete in latest sap versions.

Better use AT NEW statement

It will do the same function.

see the doc

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.

sort sflight by carrid connid.

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.

Cheers,

Simha.

Hi Chandra,

You mean to ask in Modules.Right.The event which can control the execution of a Modules are,

Extras:

1. ... ON INPUT

2. ... ON REQUEST

3. ... ON *-INPUT

4. ... ON {CHAIN-INPUT}|{CHAIN-REQUEST}

5. ... AT CURSOR-SELECTION

2 .Field MATNR Module matnr_validate ON REQUEST .

Effect

With this condition, module mod is called only if the value of the screen field MATNR has been changed by input after the event PBO. It is considered as input if the existing input is overwritten with the same value or if the initial value of the field is entered explicitly.

But there is no event ON CHANGE-REQUEST.
