Hi
The BAPI doesn't call the fm FI_DUPLICATE_INVOICE_CHECK in order to check the posting: I was the same problem and I solved it by the BTE RWBAPI01, usually used to transfer the extension data.
If your release is ECC 6 u can also use the BADI acc_document (method change).
If you use the BTE u need to use a record dummy for extension in order to trigger the BTE
This is the code (Step 1):
.FUNCTION Z_SDFI_INTERFACE_RWBAPI01.
*"----------------------------------------------------------------------
*"*"Interfaccia locale:
*" TABLES
*" IT_ACCIT STRUCTURE ACCIT
*" IT_ACCCR STRUCTURE ACCCR
*" RETURN STRUCTURE BAPIRET2
*" EXTENSION STRUCTURE BAPIACEXTC
*" IT_ACCWT STRUCTURE ACCIT_WT
*" CHANGING
*" VALUE(DOCUMENT_HEADER) LIKE ACCHD STRUCTURE ACCHD
*"----------------------------------------------------------------------
............................
LOOP AT IT_ACCIT WHERE KOART = 'K'.
IT_ACCIT-XUMSW = 'X'.
MODIFY IT_ACCIT.
SELECT SINGLE REPRF FROM LFB1 INTO _REPRF
WHERE LIFNR = IT_ACCIT-LIFNR
AND BUKRS = IT_ACCIT-BUKRS.
IF SY-SUBRC <> 0.
CLEAR _REPRF.
ENDIF.
READ TABLE IT_ACCCR WITH KEY POSNR = IT_ACCIT-POSNR.
