A TA1 interchange acknowledgement is a message transmitted by the receiver of EDI data back to the sender that contains information about the acceptability of the interchange segments of the original message. The interchange acknowledgement reports whether the interchange segment was valid (accepted) or invalid (rejected) and, if appropriate, identifies errors.
The TA1 segment appears following the interchange segment in X12 messages. It can appear between the ISA and GS segments of the file. It is a fixed length, and contains these five elements:

To set up TA1 interchange acknowledgements, you must:
At the partner site, create the TA1 interchange acknowledgement map, using the Build Acknowledgement screen. This procedure is similar to that used to build the 997 functional acknowledgement map.
At the originating site, include a request for a TA1 interchange acknowledgement in the trade agreement for all outbound EDI maps that require an interchange acknowledgement.
At the originating site, create a TA1 reconciliation map to read the interchange acknowledgement and report on the ISA segment of the original message.
At the originating site, the ISA14 element value must be set to 1 in the outbound EDI message. This indicates that this message requests an Interchange Acknowledgement.
Each of these processes is described in subsequent sections.
