I need to pay an AP Voucher that has already been entered. But when I go to select items to pay in AP-F, it says "This vendor has no open invoices." When I go to AP-B Enter Voucher to review it, I am able to find the voucher listed, however the system says, "Some of the data necessary to change or back out this transaction is no longer present. To make changes you must enter a new transaction." This expense item is still showing in the Detailed Trial Balance. If I enter it again, it will duplicate the expense amount. What do I do?

Thanks so much, Lynn. I appreciate the quick response. Now if only I can prevent these weird problems from happening to me in the future...
