ORDERS05 IDoc create CR Pricing Credit Quantity issue

Question

Hello All,
I'm stuck, I can't figure out how to put the quantity on a Pricing Credit (Sales Document Type CR) when creating it from an ORDERS05 idoc using inbound process code ORDE.  The entire order is created properly, but it does not have a Quantity, therefore it is incomplete and well, you know, quantity is kinda important for a pricing credit. I've tried all fields in the E1EDP01 segment of the idoc, none of them seem to work.  You see, a CR pricing credit doesn't have schedule lines so populating the menge or the bmng2 field of the idoc has no effect.  I've also tried moving the quantity from the bmng2 segment to the zmeng field using the VEDA0001 user exit.  See in VBAP when creating a pricing credit manually, the zmeng field is where the quantity shows up so I figured if I populated the DXVBAP-ZMENG field in the exit (I've tried zxvedu03 and zxvedu09).  I put in very simple code ...
IF contrl-mescod = '180' AND segment-segnam = 'E1EDP01'.
  lt_vbap-zmeng = segment-sdata+29(15).
ENDIF.
...but I wouldn't be writing here if that had worked.
Has anyone created a pricing credit from an IDoc using IDOC_INPUT_ORDERS?
Thanks for any clues or solutions,
Greg

If someone comes up with a better solution let me know, but I've decided to do the following:
Place an invisible field on the sales order additional data b tab and make it a direct reference to VBAP-ZMENG.  Then use user-exit zxvedu04 to activate that screen and populate my field (which is actually the main vbap-zmeng field).  I couldn't figure out how else to do this and I know this seems hokey, but it does work and I've tired of beating my head against this.
  CASE dlast_dynpro.
    WHEN '5003'.
      lt_vbap = dxvbap.
      READ TABLE gt_processes_lines WITH KEY posnr = lt_vbap-posnr.
      IF sy-subrc <> 0.
        PERFORM dynpro_setzen(saplveda) USING 'BDC_OKCODE' panel-pzku.
        PERFORM dynpro_new(saplveda) USING programm_auftrag
                                           '4003'  "DYNPRO-PZKU
                                  CHANGING dlast_dynpro.
        lv_zmeng = lt_vbap-zmeng.
        PERFORM dynpro_setzen(saplveda) USING 'VBAP-ZMENG'
                                              lv_zmeng.
        gt_processes_lines-posnr = lt_vbap-posnr.
        APPEND gt_processes_lines.
        CLEAR: gt_processes_lines, lv_date.
        PERFORM dynpro_setzen(saplveda) USING 'BDC_OKCODE' 'BACK'.
      ENDIF.
  ENDCASE.
