IDOC ORDERS02 E1EDP02 QUALF 001: Purchase Order at Item level not inserted

Question

Hi all,
I try with an ORDERS02 IDoc in segment E1EDP02 with QUALF 001 to insert a customer purchase order number at item level different from the one passed in E1EDK01 QUALF 001 and I expect to insert additionally to the VBKD record for POSNR 000000 one for my item line.
This additinal VBKD record is not inserted and I do not get this customer purchase order number in my sales order.
Does any one know what to do?
Thanks in advance.

Answer 1

To take over customer purchase order number on item level like the one for the ship-to-party (to treat a QUALF=001 for BSTKD like the QUALF=044 for BSTKD_E) seems to be unpossible.
Within IDOC_INPUT_ORDERS
LVEDAF5M: FILL_E1EDP02
WHEN '044'.
*- Bestellnummer des Warenempfängers -
*- purchase order number consignee -
      PERFORM IDOC_MOVE USING E1EDP02-BELNR XVBAP-BSTKD_E D_FLAG_P-PBES.
We need to have
WHEN '001'.
*- Bestellnummer des Warenempfängers -
*- purchase order number -
      PERFORM IDOC_MOVE USING E1EDP02-BELNR XVBAP-BSTKD D_FLAG_P-PBES.
this is calles from
LVEDAF2U:
*- Auftragsposition Referenzen -
*- item reference data -
      WHEN 'E1EDP02'.
       MOVE IDOC_DATA-SDATA TO E1EDP02.
       PERFORM ZUORDNEN_ORDERS_E1EDP02.
*-Zusätzliche Daten aus IDOC-Struktur (Kundenerweiterungen)----
*-additional data's from IDOC (customer exit)----
       SY-SUBRC = 0.
       PERFORM CUSTOMER_FUNCTION_IDOC USING IDOC_DATA.
This calls
CALL CUSTOMER-FUNCTION '001'
So IDOC-DATA-SDATA is allready in E1EDP02
but it is not sufficient to do the call needed like stated above within EXIT_SAPLVEDA_001 since
I expect a result in VBKD, not in VBAP, and BSTKD is not like BSTKD_E a field of XVBAP.
In LVEDAF16, LVDEAF1C, LVEDAF27 AND LVEDAF4N the field is taken over into the screen but we have no chance to forward it to there
and to enhance there. Last one seems most interesting since it is for VA01!
It could be to enhance EDIT_SAPLVEDA_002 but how to forward the content to this field if it is a VBKD
field and all VBKD fields are statically added to VBAP fields in the program and not in the dictionary.
That would cause to append a parking field in VBAP or require to modify the code!
Any better ideas?
