I attempted to amend an AP invoice by changing the invoice date; however, I encountered this message, “Invoice Date cannot be later than the Check Date [xx/xx/xx]”. Why?


The message appears when the AP invoice has been partially/fully paid. Verify the Inv Balance value in the AP Invoice Transactions ► Information tab. If the invoice balance is less than the invoice amount, then payment has been processed for the invoice. The [xx/xx/xx] is the date of payment. AccountMate does not allow the invoice date to be later than the check date. A similar validation message is displayed if you attempt to change the invoice Post Date to a date that is later than the check date.
