The types of transactions which flow through the cheque book, but are not added through this function, are:
Even though the transactions were not added or edited through the cheque book function, use the cheque book to cancel any of these transactions. If the transaction is a creditor payment, unallocate the payment from any purchases prior to cancelling it.
If the transactions are bank fees or bank interest, these transactions are entered through the Bank Reconciliation screen and they will default to being reconciled once added.
Bank fees and interest can also be added via the cheque book, if desired.
A bank fee or interest entry cannot be cancelled if they are partly or completely reconciled.
The cheque book list has a Search field for all these types of transactions for filtering purposes.
