Credit memo posted to GL with distributions showing $0.0 and CM is $33,088.00. How do I correct it?

This one really has me stumped.

We are on 11i fully patched.

We have a credit memo put in the sytem in Oct. 13. The distributions are at $0.0 and the CM says it is partial accounted and needs revaluation. The period is closed. The last distribution line says 01-NOV-2013, but I can't reverse it or cancel or delete any thing about this CM. On and it has been 'paid' on a payment already.

This was supposed to be a return to supplier, but the system didn't create the debit memo so we entered the Credit memo. The original invoicie was entered with the correct PO number but the CM wasn't entered with any PO number. So on the Accrual Reconciliation Report I can see the Invoice with the PO number and I have this CM listed with A/P NO PO.
