Re: AT Statement in Nested Loops

at event will not work properly for loop at itab with condition.

It will work for loop at itab without any condition.

You can add this logic to your program..

TABLES: VBUK, VBUP.
DATA: itab_vbuk TYPETABLEOF VBUK WITHHEADERLINE,
       itab_vbup TYPETABLEOF VBUP,
       itab_vbup1 TYPETABLEOF VBUP,
       wa_vbup1 likelineof itab_vbup1,
       wa_vbeln(10) typec.
DATA: counter TYPEi.
START-OF-SELECTION.
   SELECT * FROM VBUK INTOTABLE  itab_vbuk .
   SELECT * FROM VBUP INTOTABLE  itab_vbup .
 
   sort itab_vbuk by vbeln.
   sort itab_vbup by vbeln.

   LOOPAT itab_vbuk.
     clear itab_vbup1.
     itab_vbup1[] = itab_vbup[].
     delete itab_vbup1 where vbeln ne itab_vbuk-vbeln.
     wa_vbeln = itab_vbuk-vbeln.
     LOOPAT itab_vbup1 into wa_vbup1.
       IF wa_vbup1-wbsta = 'C' .
         counter = counter + 1.
       ENDIF.
       ATLAST.
         WRITE:/ wa_vbeln, counter.
         CLEAR counter.
       ENDAT.
     ENDLOOP.

   ENDLOOP.
