I have a customer who gets an error after they save a started bank reconciliation. They create a new bank rec, the run the suggest lines, then click ok, which saves the reconciliation. When they then go back into the same reconciliation, they get an error “A transaction must be started before changes can be made to the database”. They then have to delete the bank rec.
