BAPI_PO_CREATE1 ECC error message ME045

Question

Hi,
I'm creating a Purchase Order via BAPI_PO_CREATE1 but in tb_return I have always an error message (ME045): "ME045 G/L account XXXXXX cannot be used".
I try to do the same purchase order with same data throught t-code ME21N and it's possibile save PO because there aren't errors
I see abap source of BAPI and error happens in this section:
Include: LMEXFF0
Form: feldauswahl_fehler
Code:
  SELECT SINGLE * FROM tmodp WHERE spras = sy-langu
                             AND   fauna = 'SKB1-FAUS1'
                             AND   modif = tmodp-modif.
  IF sy-subrc EQ 0.
    MESSAGE e045 WITH skb1-saknr t162k-knttp tmodp-ftext.
  ELSE.
    MESSAGE e045 WITH skb1-saknr t162k-knttp tmodp-modif.
  ENDIF.
Thanks for help

Answer 1

Try switch E:ME045 - G/L account & cannot be used (please correct) to warning in the Backend using /OME0 (note 815849, )
Maybe that field group settings for additional accounting in the backend ta FS02 - G/L account master, OME9 - AccAssCat
send by SRM PO are not 'Opt.Entry', but 'Display' or 'Hidden'. Check this also.
