ABA Fixed File format:

The bank requires a predefined Australia Domestic Payments payment file definition known as ABA to be established at the Bank Admin level. This file definition will apply to a payment method of ACH or BKT only.  The payment method will be determined in the payment file definition identified when a user uploads a file and the file upload process will set the payment method for this file based upon the associated payment file definition selected – ABA-ACH or ABA-BKT.

There are some specific details about the ABA file format that are important to the file upload process.

An ABA file will contain only one “set” of payment instructions – i.e., only one ‘set’ of Descriptive, Detail and Batch Control records.) The records in the ABA file to be uploaded must follow a defined order. Each batch must:

·         Start with a Descriptive Record.

·         Contain one or more Detail Record(s).

·         End with a Batch Control Record.
