What is an EDI 860?

An EDI 860 is a Purchase Order Change Request, sent by the retailer to modify an order it has already placed. It can change quantities, add or cancel lines, move the delivery window, or redirect the ship-to location. The supplier is expected to acknowledge the change, and the revised terms replace the original for compliance scoring.

An 860 that goes unread is a common cause of an otherwise avoidable penalty. The delivery window in the change request is the one that counts, so a warehouse working from the original 850 can ship exactly on the old schedule and still be late.
