Hi,
When u use AT NEW it will take the all the fields till the field mentioned in AT NEW as key. So in ur case u need combination of matnr charg. So even if plant changes it triggers the event.
There are 2 way.
1. Changing field order in internal table.
If u r using select to get the data the it is not suggested as the field order in select should be same as they appear in data base table.(Performance issues)
2. Take one extra internal table and pass the data to that.
LOOP AT itab_mchb INTO wa_mchb.
CLEAR wa_mchb_temp.
wa_mchb_temp-matnr = wa_mchb-matnr.
wa_mchb_temp-charg = wa_mchb-charg.
wa_mchb_temp-werks = wa_mchb-werks.
wa_mchb_temp-clabs = wa_mchb-clabs.
APPEND wa_mchb_temp TO i_mchb_temp.
ENDLOOP.
Now
SORT i_mchb_temp BY matnr charg.
LOOP AT i_mchb_temp INTO wa_mchb_temp.
SUM.
AT END OF charg.
APPEND wa_mchb_temp TO i_final.
ENDAT.
ENDLOOP.
Thanks,
Vinod.
