This is the X12 860, formally titled Purchase Order Change Request - Buyer Initiated. It lets a buyer amend a purchase order already in the supplier's hands: quantity adjustments, price corrections, rescheduled delivery dates, added or removed line items, or full cancellation, and it can confirm acceptance of seller-proposed changes. Trading partners require it so the order of record stays identical on both sides and invoices reconcile against the amended order rather than the original. Always sent by the buyer to the supplier, referencing the original 850; the supplier accepts or contests the change with an 865 Purchase Order Change Acknowledgment.
When it fires: A buyer needs to change quantities, pricing, dates, or line items on an open order, or cancel it outright, at any point in the order cycle including after partial shipment.
Common 860 rejection causes
- PO number or POC line-item references that do not match the original 850, so the supplier's system rejects or misapplies the change.
- Changes arriving after picking or shipment has begun, which the supplier can no longer execute, leaving quantity and date mismatches downstream.
- Missing or late 865 acknowledgment, so neither side can prove the amended terms were agreed before the goods shipped.
- Post-shipment price corrections sent by retailers via 860 that the supplier fails to apply before invoicing, causing invoice rejections.
