i made a table control with internal table 5 fields.i made Quantity field as an input and output field.
when report run then user change the Quantity field value.
in PAI i made this code
1st in PAI in flow logic i made this .
LOOP at ITAB. ""itab is an internal table
2nd i do this.
MODULE USER_comm INPUT.
CONTROLS: CTR TYPE TABLEVIEW USING SCREEN 102.
modify itab3 INDEX ctr-current_line.
but ctr-current_line value remain 0 due to that a short dump comes messaging that INDEX should not be 0 or less than 0.
can anybody provide me solution.
so that with each iteration of loop ctr-current_line should also increase.
thanks in advance
