Solution
Apply OSS Note 487064.
For this purpose, the structures in the BAPI have to be filled as follows:
Example call with 16 EUR and base amount 100 EUR:
- ACCOUNTPAYABLE must at least contain the item number (ITEMNO_ACC) and the vendor (VENDOR). The amount in structure CURRENCYAMOUNT is to be: AMT_DOCCUR = 16;CURRENCY = EUR;ITEMNO_ACC = 1.
- ACCOUNTGL is only provided as a dummy line item and is deleted in the AC interface. ITEMNO_ACC (2?) and G/L account (GL_ACCOUNT) are required entry fields. In CURRENCYAMOUNT, you only have to fill ITEMNO_ACC
- ACCOUNTTAX must contain ITEMNO_ACC (3?), tax account (GL_ACCOUNT) and tax code (TAX_CODE). The currency information in CURRENCYAMOUNT must contain AMT_DOCCUR = 16; CURRENCY = EUR and AMT_BASE = 100 with identical ITEMNO_ACC (3?).
