how to increase number in looping?

[former_member635273]

i have tried looping number. and every looping i add 1 to variable. but, the output still 1.

LOOP AT it_res.
      MOVE-CORRESPONDING it_res TO wa_item.
         wa_item-id = wa_item-id + 1.
      APPEND wa_item TO it_item.
ENDLOOP.

i've tried "add 1 to wa_item-id " but it's same.

Thanks in advance.

If you debug, you understand in an instant. Remember that a watch point can be used to detect the change of a variable wherever it happens. Faster than asking.

When using LOOP AT, SY-TABIX contains the row number of the current row in the table.

Your problem is when you do the move-corresponding, WA_ITEM-ID is cleared because not part of the IT_RES structure.

WA_ITEM-ID = WA-ITEM-ID + 1

gives always 1
