Completed Purchase Orders showing on Purchases Clearing Report

SUGGESTED

Several months ago I cleaned up the Purchases Clearing Report. It was current and accurate. I ran it yesterday and there are old (anywhere from 1-13 years old) completed purchase orders showing on the report. Most of them are showing as a scenario where the quantity ordered equals the quantity received, but the qty invoiced is either zero or off by one, however all of these PO's show as completed when I open the PO. And we were invoiced for them. I have run Rebuild/Resort files for PO and no change. I went into one of the POs in a backup of the live company and deleted the line item showing on the Purchases Clearing report. Accepted the PO, and it did remove it from the Clearing report. But that can't be a good way to remedy this. It seems like a glitch has occurred. I would rather not purchase old POs if I don't have to. Also, none of the old POs are showing on the Purchases Clearing in Open PO format report. That one is accurate. Any thoughts?
