BAPI_ACC_DOCUMENT_POST with Negative Exchange Rate

[Former Member]

Hi, SAP Community.

I hope you can help me with this case.

Scenario: One FI document needs to be reversed. This document has negative exchange rate(KURSF) in table BKPF.

Problem: How to post a reversal for this document using BAPI_ACC_DOCUMENT_POST that will result to a new document with negative exchange rate in table BKPF?

Currently, we are able to do reversal with no errors however, the exchange rate in BKPF comes out as positive. When we call BAPI_ACC_DOCUMENT_POST, inside the currencyamount we have 2 exchange rates: positive and negative. Negative rates have been placed to column EXCH_RATE_V. No errors encountered. Everything is correct except for the positive exchange rate in BKPF. How will I make the new entry in BKPF store a negative exchange rate just like the original document?

Thank you.
