Need to Modify VBEP-CMENG using SD_SALESDOCUMENT_CHANGE

Hi Friends,

We are facing problem while using SD_SALESDOCUMENT_CHANGE Function Module.

Our requirement is we need to modify the Rounded Qty through Z report for specific Sales order Schedule lines.

When we try to use the above function module and pass quantity in table SCHEDULE_EX - CORR_QTY, it is not working.

Below are the addition Parameters passed to these table.

      ls_schedule_ex-operation  = '004'.
       ls_schedule_ex-doc_number = g_it_data-vbeln.
       ls_schedule_ex-itm_number = g_it_data-posnr.
       ls_schedule_ex-sched_line = g_it_data-etenr.
       ls_schedule_ex-corr_qty   = ls_schedule-req_qty.
       APPEND ls_schedule_ex.

Note : Checked through debugging, as soon as the function module is called , SCHEDULE_EX table is refreshed and cleared.
