Removing A/P Vendor Credits from A/P Aging

If you have A/P credits that a vendor has issued a check for you can choose to remove them from A/P Aging.

Create a non-A/R deposit to an account valid for that supplier.
Enter an invoice for the supplier with an invoice # something like "CHKxxx" and post it to the same account.
Create a check run with the credit memo and invoice which will net to -0-, however, produce a remittance showing the two clearing against each other.
