Re: BAPI_SALESORDER_CHANGE doesn't change qty but sum new qty

You would also need to pass the Schedule line number to tell the order which schedule line to update. Otherwise, I believe it would add a new schedule line, which would result to addition to the quantity.

You are also missing the Line Item number fro the Schedule line in the Change table (X structure).

        schedule_lines-itm_number = lv_vgpos.

        schedule_lines-sched_line = lv_schedule_line.

        schedule_lines-req_qty    = i_act_weight.

        APPEND schedule_lines.

 

 

        schedule_linesx-updateflag = 'U'.

        schedule_linesx-itm_number = lv_vgpos.

        schedule_linesx-sched_line = lv_schedule_line.

        schedule_linesx-req_qty = 'X'.

        APPEND schedule_linesx.
