PO Change Acknowledgment

Supplier → Retailer

Your response to an 860 — accept or reject the retailer's change.

The 865 acknowledges a purchase-order change (860): you confirm the change, propose your own, or reject it. It closes the change loop the 860 opened.

⚠ Where it bites

Respond within the retailer's window; silence is often treated as acceptance.
