In an attempt to record an electronic payment I accidentally did an AP-B as a manual check.  Before printing, but after entering through all phases, I realized this is not what I should be doing.  When asked if I wanted to print the check I said NO.  The transaction posted correctly by first debiting the expense and crediting AP, then reversing that.  It also debited AP and credited the cash account, and reversed that out.  The problem is that the vendor shows a credit balance of the invoice amount in an aging report, but if I attempt to select invoices to be paid it does not show a credit.  Can someone advise how to zero out the vendor account?
