Implementation Acknowledgment (ASC/X12)

The implementation acknowledgment document builds upon the Implementation Acknowledgment (999) transaction set. It reports on the following 2 errors:

At a minimum, the implementation acknowledgment reports syntax errors; if the implementation guideline does not contain any semantic rules, the acknowledgment behaves similar to a functional acknowledgment but using the IK3, IK4 and IK5 instead of the AK3, AK4, AK5 segments (used in the functional acknowledgment). With semantic rules, the implementation acknowledgment reports not only the item in error, but also the situational context under which the error occurred. This context is reported using the Context (CTX) data segment.

The diagram below is an example of an implementation acknowledgment generated by Framework EDI (FREDI). The acknowledgment is a report on errors of a purchase order. The first group of IK3/IK4 reports a syntax error, while the second group of IK3/IK4/CTX reports on a situational error.

The following discusses how the implementation acknowledgment is processed:

Generating the Implementation Acknowledgment. By default, FREDI does not generate the implementation acknowledgment, so for the receiver to automatically generate an implementation acknowledgment, there are specific steps to take when programming the code that verifies the subject EDI document.
Construction of the Implementation Acknowledgment. Automatically creating the implementation acknowledgment follows a systematic approach when the subject EDI document is being traversed and scanned for errors. As each envelope and section of the document is encountered, a reporting level is created that specifies the errors found, if any.
Mapped Syntax Error Code to SEC. When FREDI encounters an error, it usually reports this error in its own standard error code (SEC), but the acknowledgment requires that specific errors are indicated by syntax error codes provided by the EDI standard. Subsequently, some SECs are automatically mapped to syntax error code so that errors are properly reported in the acknowledgment.
Action Code. The receiver specifies a code in the acknowledgment to indicate the result of the action taken on the document - either it has been received and/or accepted or rejected.
