What the 865 is
The EDI 865 — the X12 PO Change Acknowledgment — is your response to a change request — accept, reject, or counter. It travels outbound for most trading programs.
When it's sent
The 865 sits in the ordering stage of the chain, between the 850 purchase order and the 856 ship notice.
Key segments
The 865 follows the standard X12 segment layout for its functional group. Partner companion guides add the specifics — EDISQ's certified maps carry those rules per partner, so you never read the implementation guide yourself.
