NACHA type trees

This documentation describes the type trees that are included with the Pack for Financial Payments NACHA component.

Overview of the NACHA type trees
The primary type trees that are provided in the Pack for Financial Payments NACHA component provide a full definition of the records and fields that are needed to create or validate an ACH file.
Summary of ACH applications
A single batch can contain only one ACH application type. Supported ACH applications with brief descriptions are listed here. The ACH Rulebook summarizes the application types and groups them by type: consumer, corporate, or other.
Return entries
Return entries are generated by an ACH operator when data acceptance rules are violated. They are also generated by an RDFI for any reason with an appropriate return reason code specified by the ACH rules.
Notification of change entries (COR)
A notification of change entry is created in a Batch with an SEC code of COR.
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.
Analysis errors
There are no expected analysis errors for the type trees. They are analyzed for the supported ITX base product platforms, but the .dbe file is not delivered.
Additional validation recommendations
Most of the exceptions to validations affect multiple ACH types. If something is specific to one particular application type, that type is noted by its SEC code.
