Back  RFI # 51: Meaning of Received 999 Transaction

Formal vs. Informal Help Informal Formal


Todd Cochrane


For version 005010 and version 005050, when a 999 transaction is received, how does the receiver determine from the contents of the 999 whether the 999 is reporting "X12 Standard Conformance" or the 999 is reporting "Implementation Guide Conformance" -- particularly when (a) no errors are reported, and/or (b) no implementation guide-based errors are reported ?


There is no indicator in the 999 transaction set that describes whether it is reporting X12 Standard or Technical Report Type 3 (i.e. Implementation Guide) conformance. However, by definition, the 999 is specifically for use in reporting Implementation Guide conformance. (from the 999 Implementation Acknowledgment, purpose and scope, The transaction set can be used to define the control structures for a set of acknowledgments to indicate the results of the syntactical and relational analysis of the electronically encoded documents, based upon a full or implemented subset of X12 transaction sets. ) Since compliant Implementation Guides must be compliant with the X12 standard from which they are created, the reporting of compliance (or non-compliance) with an implementation Guide includes compliance with the X12 standard. The 999 Transaction Set is used for reporting on TR3 conformance and must not be used for reporting only X12 Standard compliance.


The official response to a formal RFI is a letter from the current ASC X12 chair. This website often displays a summary of the RFI. Click here to view a PDF of the letter for this RFI.

Further Discussion: Note 1/0400 (from the 999 X12 Standard Transaction Set) states, The data segments of this standard are used to report the results of the syntactical analysis of the functional groups of transaction sets; they report the extent to which the syntax complies with the standards or proper subsets of transaction sets and functional groups as expressed in compliant implementation guides.
