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).

If an existing payment type is enabled to allow electronic payments, 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. |
