Credit Card Provider Reimbursement from AP

Summary:

We have a requirement to generate invoices to credit card provider for reimbursement of transactions charged to the corporate card.

Content (required):

The requirement of the corporate card provider is to include the full credit card number as part of the payment file to properly allocate the transaction to the proper credit card account.

We use Concur so the corporate cards are not currently stored in Oracle.

Capturing the credit card number in another field will not be PCI compliant.

Any suggestions on where we can store this credit card number for employees that are accessible as part of the payment process? We make our payments to the bank using an ACH transaction.
