In an X12 interchange, an Interchange Acknowledgment (TA1) notifies whether the control header and trailer envelope that surrounds one or more functional groups is received successfully. Also, the TA1 segment reports the syntactical accuracy of the envelope. The TA1 does not report the status of the functional groups and transaction sets within the interchange envelope.

Module for EDI provides a built-in service, wm.b2b.edi:generateX12TA1, to generate a TA1 acknowledgment manually. While generating the TA1 acknowledgment, this service provides the option to include a functional acknowledgment, as well. To generate a TA1 with or without an FA, you invoke the generateX12TA1 service from the service that you create to process an EDI document.

For more information about the wm.b2b.edi:generateX12TA1 service, see webMethods Module for EDI Built-In Services Reference.

TA1s can also be generated automatically using the X12TA1Generation/autoGenerateX12TA1 EDITPA variable. For more information, see webMethods Module for EDI Installation and User’s Guide.
