Hi
After park invoice with tcode MIR7, exchange rate cannot changed if invoice line related to PO exist.
I have tried to use bapi_incominginvoice_change to modify the rate and it seem okay. The header is modified and posting with the new rate worked.
Does anyone performed similar before？Any side effect ?
I just afraid there are some reasons SAP disabled the update on standard system and this changes will cause data inconsistency.
On our system, 'fixed exchange rate' is not used in PO.
Thanks in advance.
Michael
