If you don't use BankRec, then you can do the same process in Adagio Payables. Open the Check Reconciliation function and look for the check in question. If it has a status of Outstanding, then you can choose to Reverse the check - this will generate the reversing GL entries, including cash invoice distributions. If the check paid invoices, then those invoices will be restored as if they were not paid by the check in the first place.

If the bad check has been Cleared, Voided, or have any status other than Outstanding, then it is too late to Reverse the check in this way, and you will have to do the entry manually, with AR adjustments and GL journal entries, depending on what needs to be corrected.
