999 - Implementation Acknowledgment
FUNCTIONAL GROUP=FA

This X12 Transaction Set contains the format and establishes the data contents of the Implementation Acknowledgment Transaction Set (999) for use within the context of an Electronic Data Interchange (EDI) environment. 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. The encoded documents are the transaction sets, which are grouped in functional groups, used in defining transactions for business data interchange. This standard does not cover the semantic meaning of the information encoded in the transaction sets.

Notes

1/0100

Neither the 997 nor the 999 Acknowledgment shall be acknowledged, thereby preventing an endless cycle of acknowledgments of acknowledgments. Nor shall a Implementation Acknowledgment be sent to report errors in a previous Implementation Acknowledgment.

1/0100

There is only one Implementation Acknowledgment Transaction Set per acknowledged functional group.

1/0100

Only one acknowledgement, either a single Transaction Set 997 or a single Transaction Set 999, should be generated for a functional group unless mutually agreed upon.

1/0200

AK1 is used to respond to the functional group header and to start the acknowledgment for a functional group. There shall be one AK1 segment for the functional group that is being acknowledged.

1/0200

The Implementation Acknowledgement is generated at the point of translation, intended for the originator (not any intermediate parties).

1/0200

The Functional Group Header Segment (GS) is used to start the envelope for the Implementation Acknowledgment Transaction Sets. In preparing the functional group of acknowledgments, the application sender's code and the application receiver's code, taken from the functional group being acknowledged, are exchanged; therefore, one acknowledgment functional group responds to only those functional groups from one application receiver's code to one application sender's code.

1/0300

AK2 is used to start the acknowledgment of a transaction set within the received functional group. The AK2 segments shall appear in the same order as the transaction sets in the functional group that has been received and is being acknowledged.

1/0700

The CTX Segment shall be used to disambiguate a reported error that is dependent on context.

1/0800

If any implementation guide errors have been reported in IK3 or IK4, then code I5 shall be reported in the IK5 Segment.

Comments

1/0400

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. They do not report on the semantic meaning of the transaction sets (for example, on the ability of the receiver to comply with the request of the sender).
