Our new bookkeeper made a small mistake and I'm hoping somone can make sense of this and help us fix it.
 
1. A credit voucher was received from a vendor to apply against some returned product that was properly processed through PO-C.
 
2. In the AP-C Enter PO Invoices Screen, after properly selecting the vendor and entering the credit PO number, she marked the "payment" as COD instead of as an invoice.  Thus, by entering a negative dollar amount in the CheckAmount field, we improperly debited Cash G/L account and credited A/P.  I probably could have saved it at this point but...
 
3. The bookkeepers "Fix" was to void the COD "Check" in AP-Q before I knew something was wrong.  This, again, debited Cash G/L account and credited A/P because "Voided" check was negative.
 
Ouch.
 
Any takers?
