Acknowledgement records

An acknowledgement (ACK or ATX) entry is created by an RDFI to notify ODFI of receipt of CCD or CTX, if such is requested by the CCD or CTX entry.

A refused acknowledgement entry is created by the ODFI to refuse an ACK that is incorrectly routed, incorrect, or incomplete.

The Pack for Financial Payments does not generate these automatically, but the type tree provides the appropriate definition to allow you to create your own map for them. These entries are defined by specific SEC codes, ACK and ATX. They are listed in the partitioned group, Batch Group, as the standard application types that are defined by this three letter code.

The NACHA component examples for IBM Sterling B2B Integrator come with an ACH Deenvelope service scenario to generate an ATX message from an Inbound CTX.
