EDI 997 Functional Acknowledgment

Functional Group FA

X12C Communications and Controls Subcommittee

The purpose of this standard is to define the control structures for a set of acknowledgments to indicate the results of the syntactical analysis of the electronically encoded documents. 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.

What is an EDI 997?

An EDI 997 Functional Acknowledgment serves as a response to an individual EDI message or group of messages. It contains information about the receipt of the upstream transaction, such as whether it has been accepted, accepted with errors or rejected (AK5 segment), if there are any segment errors (AK3 segment) or if there are any data element issues (AK4 segment).

How is an EDI 997 used?

For example, Vendor A sends Retailer B an EDI 810 Invoice. Retailer B responds with an EDI 997 Functional Acknowledgment, which communicates to Vendor A that their EDI 810 Invoice was received and is syntactically valid.
