Supported TA1 Codes

The X12 TA1 technical acknowledgment reports the status of the processing of an interchange header and trailer. When the ISA and IEA of the X12-encoded message are valid, a positive TA1 ACK is sent, whatever the status of the other content is. If not, TA1 ACK with an error code is sent.

AckMan analyses each ISA header as it reads the EDI document along. If the ISA can be rejected, a TA1 is generated immediately without waiting for the IEA trailer.

The following table indicates which error codes specified by the X12 specification are supported in ediFabric AckMan and which are unsupported. The values for TA104 are as follows:

A = Accept

E = Interchange accepted with errors

R = Interchange rejected/suspended
