Book adjustment entry against Credit Card Issuer

We are experiencing an issue where certain credit card transactions are being rejected and therefore are not interfaced into the system. Because Oracle Expenses does not currently provide notifications or alerts to identify these rejected records, we are evaluating alternative methods to detect such exceptions as part of our month-end reconciliation procedures. Our intended approach is to reconcile the corporate card issuer invoices generated in Accounts Payable (AP) against the monthly credit card statement and, where discrepancies are identified, record a manual invoice in AP to account for the variance.

The challenge we are facing is that the corporate card issuer is configured as a separate expense entity in Fusion, resulting in the issuer being created as a party in the system. However, to record a manual invoice, the same credit card provider must also be defined as a supplier.
