In A/R, entered an invoice twice in December, and subsequently voided one of the occurrences during month-end review. Open A/R report and general ledger in balance at year-end, both correctly showed one occurrence of the invoice as open. Customer check paying the invoice received and we're trying to post that cash receipt. In A/R - Post Receipts, both occurrences show as voided, so can't post a receipt against the invoice. Accounts Receivable Open Invoice Report still shows invoice as open. How do I get one of the occurrences to not show as voided in Post Receipts?
