When importing customer payments in D365 F&O from camt054C files (payment method ISO20022) the incorrect exchange rate is used. The journal uses the system exchange rate in D365 instead of the exchange rate from the bank statement file (camt054C). Need to import the bank exchange rate to have the correct amount posted in the journal for the bank transaction.
On the Vendor side for Camt.054D debit notification, during import, we have a parameter to allow import of the exchange rate from the camt.054D file.
Please consider the same option on the Camt.054C credit notification import.
