Most common alongside 865
This is the seller-initiated use of the 865 transaction set. Instead of acknowledging a buyer's 860, the supplier proposes its own changes to an open purchase order, such as revised delivery dates, adjusted quantities, or updated prices. Buyers require it so supply-side changes enter the order of record through EDI rather than email or phone, keeping the purchase order version both parties fulfill against consistent. The supplier sends it unprompted to the buyer to request or notify changes to a purchase order the buyer previously placed.
When it fires: A supplier determines it cannot fulfill an open order as written, for example a stockout, a price update, or a slipped ship date, and issues an 865 proposing the change.
Common 865 rejection causes
- Transaction Set Purpose Code set incorrectly, so the buyer's system processes a seller-initiated change request as an acknowledgment of a change it never sent.
- Change requests referencing purchase orders the buyer has already closed, received, or invoiced, which the buyer's system rejects or ignores.
- Restated line values that conflict with the buyer's current version of the purchase order, surfacing later as ASN or invoice discrepancies.
- Missing original purchase order number, leaving the buyer unable to match the request to an open order.
