Can I manually settle a rebate claim if supplier sends check

Summary:

Instead of Oracle creating a debit memo to settle a rebate claim, we receive payments from suppliers on a regular basis based on what they calculated as the rebate they owe us. Can we apply a received payment or credit memo to the a rebate program in order to settle a claim in the Supplier program? Can I manually move a claim from Settlement Pending to Closed.
