EDI TA1 Format Example

EDI TA1 Interchange Acknowledgment


What is EDI TA1 Interchange Acknowledgment?

The EDI TA1 Interchange Acknowledgment is used to verify the syntactical accuracy of the envelope segment of the X12 interchange. The TA1 will indicate that the file was received as well as indicate what if any errors existed within the envelope segments of received X12 files. The TA1 verifies the envelope only.

Encompassed in the TA1 are the interchange control number, interchange date and time, interchange acknowledgment code, and the interchange note code. Whether the EDI document does or does not contain an error, the interchange acknowledgment will contain the ISA, TA1, and IEA segments.

A = Interchange Accepted When the envelope of the EDI document does not contain an error, the TA1 segment will have an Interchange Acknowledgement Code of ‘A’ (Accept) followed by a three-digit code of ‘000’, which indicates that there were not any errors. 

E = Interchange Accepted with Errors

R = Rejected If the EDI document contains an error at the interchange level, such as in the Interchange Control Header (ISA) segment or the Interchange control trailer (IEA), then the TA1 segment will have an Interchange Acknowledgement Code of ‘R’ (Rejected) accompanied by specific error codes.

Trading Partners can elect when to generate the TA1: Always, On Error, or None. If None, no TA1 is generated regardless of content.

TA1 Error Codes

When the TA1 Status is A, the TA1 Code is 000. When the TA1 Status is either R or E, the TA1 Code attribute indicates the type of error that the module encountered. The following table lists the error codes and their meanings.
