Data Transfer from Sales Order to Purchase Requisition

Question

We are trying to transfer data from Sales Order to purchase requisition in an individual purchase scenario.
We want to copy value in KUWEV-KUNNR in Sales Order and paste in CMMDA-KUNNR on purchase requisiton.
So in user-exit "USEREXIT_MOVE_FIELD_TO_ME_REQ" on include "MV45AFZB" we added the following code:
FORM USEREXIT_MOVE_FIELD_TO_ME_REQ.
DATA:   BEGIN OF IT_VBEP OCCURS 0,
        VBELN LIKE VBEP-VBELN,
        BANFN LIKE VBEP-BANFN,
        KUNWE LIKE VEPVG-KUNWE,
        END OF IT_VBEP.
DATA: BEGIN OF TI_VBAK OCCURS 0.
        INCLUDE STRUCTURE IT_VBEP.
DATA: END OF TI_VBAK.
    SELECT A~VBELN   B~KUNWE
      INTO CORRESPONDING FIELDS OF TABLE IT_VBEP
    FROM  VBAK AS A INNER JOIN VEPVG AS B
                          ON B~VBELN = A~VBELN
    WHERE A~AUART EQ 'PDIR'.
   LOOP AT EBKN.
       LOOP AT IT_VBEP.
            IF IT_VBEP-VBELN = EBKN-VBELN.
              IT_VBEP-BANFN = EBKN-BANFN.
            ENDIF.
            MODIFY IT_VBEP.
       ENDLOOP.
   ENDLOOP.
*Break-point.
SORT IT_VBEP BY vbeln.
LOOP AT IT_VBEP.
  IF EBAN-BANFN = IT_VBEP-BANFN.
    EBAN-KUNNR = IT_VBEP-kunwe.
    MODIFY EBAN.
  ENDIF.
ENDLOOP.
* Example
* EBAN-LIFNR = zzfield1.
* EBKN-KOSTL = zzfield2.
ENDFORM.
*eject
Right now it turns random values on the purchase requisition field.

Answer 1

Hi,
Why are you using only the following line to read the VBEP table?
WHERE A~AUART EQ 'PDIR'.
Shouldn't you be using a sales document number or something more specific than document type?
