AR2012 will unreconcile a transaction if it is changed in various ways, including just changing the cheque number.
I recommend this is changed immediately. Ever since the program was first writ...
I have noticed that when i changed the cheque number of a transaction that had been previously reconciled, it now will appear as an unreconciled transaction in your bank reconciliation.
It will affect your opening balance and you will have to re tick it to get to the correct balance and re reconcile this account with the “changed” transaction included.
This is an error as in the past you could make changes to a reconcilled tranasaction (as long as the amount was not adjusted) and it would not effect the bank reconcilation.
