I have a internal table in which has 3 fields, out of which 2 are filled. Now I want to insert some value in field 1 which is not filled.
I tried using
Loop at itab into wa_itab.
wa_itab-filed1 = 'test'.
modify itab from wa_itab.
endloop.
but still nothing is happening. I even used INSERT command but without any result.
