On the ribbon, go to Tools > Setups > Banking > Payment Type and add a new payment type called Electronic Payments (or something similar), then tick Electronic Payments.
Tick this option on any existing payment types that are to be used in electronic payments (see 
below).
 |
Note: Be aware that any payment type that is ticked for Electronic Payments means that all payments made using that type will appear in the electronic payments session. It is advisable to not tick any other payment type as Electronic Payments.
If an existing payment type is enabled to allow electronic payments, you will need to do a dummy Electronic Payments session to clear all payments previously made using this payment type, as they will appear in the first list. There is no accounting transaction related to electronic banking sessions, it is just a simple way of creating the required ABA files, and keeping track of them. |
