TA1 technical acknowledgments and error codes for X12 messages in Azure Logic Apps

Applies to: Azure Logic Apps (Consumption + Standard)

In Azure Logic Apps, you can create workflows that handle X12 messages for Electronic Data Interchange (EDI) communication when you use X12 operations. In EDI messaging, acknowledgments provide the status from processing an EDI interchange. When receiving an interchange, the X12 Decode action can return one or more types of acknowledgments to the sender, based on which acknowledgment types are enabled and the specified level of validation.

For example, the receiver reports the status from validating the Interchange Control Header (ISA) and Interchange Control Trailer (IEA) in the received X12-encoded message by sending a TA1 technical acknowledgment (ACK). If this header and trailer are valid, the receiver sends a positive TA1 ACK, no matter the status of other content. If the header and trailer aren't valid, the receiver sends a TA1 ACK with an error code instead.

The X12 TA1 ACK conforms to the schema for X12_<version number>_TA1.xsd. The receiver sends the TA1 ACK in an ISA and IEA envelope. However, this ISA and IEA envelope are no different than in any other interchange.

This topic provides a brief overview about the X12 TA1 ACK, including the TA1 ACK segments in an interchange and the error codes used in those segments. For other related information, review the following documentation:

TA1 ACK segments

The following table describes the TA1 ACK segments in an interchange:

TA1 field Field name Mapped to incoming interchange Value
TA101 Interchange control number ISA13 - Interchange control number -
TA102 Interchange Date ISA09 - Interchange Date -
TA103 Interchange Time ISA10 - Interchange Time -
TA104 Interchange ACK Code* N/A * Engine behavior is based on data element validation with the exception of security and authentication information, which are based on string comparisons in the configuration information.

The engine behavior (TA104) value is A, E, or R, based on the following definitions:

A = Accept
E = Interchange accepted with errors
R = Interchange rejected or suspended.

For more information, review TA1 ACK error codes.

TA105 Interchange Note Code N/A Processing result error code. For more information, review TA1 ACK error codes.

TA1 ACK error codes

This section covers the error codes used in TA1 ACK segments. The following table lists supported and unsupported error codes, as defined by the X12 specification, for X12 message processing in Azure Logic Apps. In the Engine behavior column, the TA104 values have the following definitions:

  • A = Accept
  • E = Interchange accepted with errors
  • R = Interchange rejected or suspended
Condition Engine behavior
(TA104 value)
TA105 value Supported?
Success A 000 Yes
The Interchange Control Numbers in the header ISA 13 and trailer IEA02 do not match E 001 Yes
Standard in ISA11 (Control Standards) is not supported E 002 Yes, if an ID mismatch exists.
Version of the controls is not supported E 003 No, error code 017 is used instead.
Segment Terminator is Invalid*

* The segment terminator can have the following valid combinations:

- Segment Terminator char only.
- Segment Terminator character followed by suffix 1 and suffix 2.

R 004 Yes
Invalid Interchange ID Qualifier for Sender R 005 Yes, if an ID mismatch exists.
Invalid Interchange Sender ID E 006 Yes, if receiving an interchange on a receive port that requires authentication.

Note: Sender ID-related properties are reviewed. If these properties are inconsistent, or if party settings are unavailable due to not being set, the interchange is rejected.

Invalid Interchange ID Qualifier for Receiver R 007 Yes, if an ID mismatch exists.
Invalid Interchange Receiver ID E 008 No*

* Supported if receiving an interchange on a receive port that requires authentication. Sender ID-related properties are reviewed. If these properties are inconsistent, or if party settings are unavailable due to not being set, the interchange is rejected.

Unknown Interchange Receiver ID E 009 Yes
Invalid Authorization Information Qualifier value R 010 Yes, if an ID mismatch exists.
Invalid Authorization Information value R 011 Yes, if party is set up or valued.
Invalid Security Information Qualifier value R 012 Yes, if an ID mismatch exists.
Invalid Security Information value R 013 Yes, if party is set up or valued.
Invalid Interchange Date value R 014 Yes
Invalid Interchange Time value R 015 Yes
Invalid Interchange Standards Identifier value R 016 Yes
Invalid Interchange Version ID value R 017 Yes, indicating that the enum value is not valid.
Invalid Interchange Control Number value R 018 Yes
Invalid Acknowledgment Requested value E 019 Yes
Invalid Test Indicator value E 020 Yes
Invalid Number of Included Groups value E 021 Yes
Invalid Control Structure R 022 Yes
Improper (Premature) End-of-File (Transmission) R 023 Yes
Invalid Interchange Content, for example, Invalid GS segment R 024 Yes
Duplicate Interchange Control Number R, based on settings 025 Yes
Invalid Data Element Separator R 026 Yes
Invalid Component Element Separator R 027 Yes
Invalid Delivery Date in Deferred Delivery Request - - No
Invalid Delivery Time in Deferred Delivery Request - - No
Invalid Delivery Time Code in Deferred Delivery Request - - No
Invalid Grade of Service - - No
