I have a balance left in my Order Entry clearning account (used for the interface between AR and OE). On reconciliation I see where one day the AR and OE interface did not agree by $1,500.06.
We have identified this as being a single invoice generated and printed by Order Entry. However while we have a physical printed copy of the invoice, we can not find the invoice in Order Entry. We have the invoice before and after but this number is completed gone. When we look at the order it says completed and shows us the invoice number. We have posted the invoice manually to AR which is why there is a clearing difference.

What could have caused this invoice to disappear from the records?
