DMR Credit with Physical Check

Accounting has asked me this…

We recently returned material to a vendor that we do not normally use. The DMR process was followed and a credit was requested. We will not be ordering any material from this vendor in the near future and we want the costs to go back towards the job. The issue is that they sent us the credit request paperwork but will be sending us a physical check to give us the money back. If we do the credit through the DMR process like we normally do it will leave a credit on their account for future orders. How do we apply this check to this credit memo when they send us the check?
