EDI 997: the Functional Acknowledgment

What the 997 is

The EDI 997 — the X12 Functional Acknowledgment — is the receipt for every document. Automatic, both directions, within minutes. It travels in both directions for most trading programs.

When it's sent

The 997 travels alongside every hop of the 850 → 855 → 856 → 810 chain, acknowledging receipt of each document within minutes.
