Open A/P Invoices

Crystal report on APINVOICE table where REC_STATUS < > 9

Received a check refund from a vendor, for a credit. How do I remove credit on open payables report and post deposit of check. Since there is a credit on the open payables report, should I create a debit memo(in AP20) as an expense to the G/L Suspense Then, a debit to cash and credit suspense account in the GL? Will the debit memo and credit cancel each other out on the payables report, or do I need to do another step? This was originally a PO invoice.
Also, if there is still a prior period invoice open on the payables report, how can the invoice be removed? We no longer owe for the invoice; it was paid in a later period.

A suggestion to keep a track of the credit that you actually received it the best approach is to create a dummy debit memo to show that you received the check. This will wash out the credit memo and thus release a possible check for other invoices. If I were creating it, I would post the dummy debit to either an Other AR or Other AP account on the GL, then when the cash is deposited make sure the same account is offset when you make the cash entry for the check. This should wash everything nicely in both the GL and AP systems and you have a better trace of what has happened. For the AP back up for the dummy debit use the refund check and a copy of the credit memo to explain what happened and also use the same for the cash transaction.
