Make sure that as a user you can activate supervisor override and it is set up in the Users and Security. If you can\'t activate supervisor override you will not be able to unpost the cheque. A Posted Cheque needs to be unposted first, and once unposted, the Bill(s) attached to it must be deleted, change the description to VOIDED for tracking or history purposes, and leave the cheque in UNPOSTED status.
