Posting Key Issue in FB01 and BAPI

[Sandra_Rossi]

• When posting a customer to bank entry in FB01, we input posting key 15, and the system correctly accepts and posts using this key.

• However, when performing the same posting through the BAPI_ACC_DOCUMENT_POST function module with the posting key set to 15, the system ignores the input and instead uses posting key 11 automatically.

Check if the KBA 3684963 - Discrepancy in posting key for customer incoming payments using BAPI_ACC_DOCUMENT_POST and... is relevant.

Hello,

Check the debit/credit indicator and account assignment data passed to the BAPI, as these fields drive the posting key determination logic

Thanks
