Sage 300 CRE does not allow for the deletion or undo on a voided check, which means you'll have to reprint. While printing checks in Accounts Payable, the check number is verified against Cash Management transactions to ensure duplicate check numbers are not used. Accounts Payable will not allow the reuse of checks that have not been voided, or any check still in the Cash Management Register. However, it is simpler to append a "1" at the end of the check number and then reset the check number.
