The user is unable to void a check if it is currently on an unposted bank rec. While performing bank recs, certain issues may be found such as a payment which was recorded in error. One could spend quite some time doing a bank rec only to find a check needs to be voided. This requires the user to delete the bank rec, void check and re-do the bank rec. This is inefficient. The user should be able to perform actions that one would normally encounter when doing a bank rec.
Note: this applies to using the bank recs with the General Ledger Setup setting, Bank Recon with Auto-Match set to FALSE.
