Delivery Creation for an STO - Help needed!!

Question

I have a requirement to update an STO ( quantities etc) , subsequently create a Delivery for the changed STO .... Now , the processing is, of an Inbound IDoc by a Custom Function Module .... Initially I was creating the delivery with a BDC on VL10B ... it was working fine whenever we processed an IDoc template in WE19 or reprocess an IDoc using BD73... Now, whenever an actual IDoc is received from the external system , the VL10B transaction fails ( GUI exception is raised).... According to OSS note 310022 , VL10* transactions do not have GUI support .. the note also mentions that the solution to the problem is to call the background program RVV50R10C ....
I used a SUBMIT within my function module to RVV50R10C supplying the necessary selection parametes ... but the problem still persists .... In ST22 .. the dump for the rfc user is appearing as:
"The termination occurred in the ABAP program "CL_GUI_CUSTOM_CONTAINER=======CP"
in "CONSTRUCTOR".
The main program was "RVV50R10C ". "
Please help !!! Top priority problem!!!

Try using the function module BAPI_DELIVERYPROCESSING_EXEC instead:
Ex:
form bapi_create_deliveries tables gtab_data structure zre029_crea_del
                            using  gw_ebeln
                            gw_tcode.
  data: ptab_request type  bapideliciousrequest occurs 0 with header line,
        ptab_items   type table of bapideliciouscreateditems,
        ptab_return  type table of bapiret2,
        pwa_request  type bapideliciousrequest.
  data: pw_error_occured,
        pwa_return type bapiret2,
        pwa_data   type zre029_crea_del.
*        gw_frgzu   TYPE ekko-frgzu.
  constants: begin of pw_msgty,
               error      like syst-msgty value 'E',
               abend      like syst-msgty value 'A',
               warning    like syst-msgty value 'W',
               info       like syst-msgty value 'I',
               success    like syst-msgty value 'S',
             end of pw_msgty.
  clear gtab_data.
  loop at gtab_data into gwa_data.
    ptab_request-document_type          = 'B'.
    ptab_request-delivery_date          = sy-datum.
    ptab_request-document_numb          = gw_ebeln.
    ptab_request-document_item          = gwa_data-ebelp.
    ptab_request-quantity_sales_uom     = gwa_data-menge.
    ptab_request-sales_unit             = gwa_data-meins.
    ptab_request-document_type_delivery = 'NL'.
    append ptab_request.
  endloop.
  call function 'BAPI_DELIVERYPROCESSING_EXEC'
    tables
      request      = ptab_request
      createditems = ptab_items
      return       = ptab_return.
* check protocol
  loop at ptab_return into pwa_return.
    if pwa_return-type = pw_msgty-error or
       pwa_return-type = pw_msgty-abend.
      message id pwa_return-id type pwa_return-type
                              number pwa_return-number.
      pw_error_occured = 'X'.
      message e001(vl) with 'Unable to create deliveries, errors with BAPI!!!'.
      exit.
    endif.
  endloop.
  if pw_error_occured is initial.
    call function 'BAPI_TRANSACTION_COMMIT'
      exporting
        wait = 'X'.
  endif.
