The X12 855 transaction set is called a Purchase Order Acknowledgement. The 855 EDI transaction code is used by sellers to confirm the receipt of a purchase order (EDI 850) from the buyer, which completely eliminates one’s need to call or fax a confirmation document. The 855 also communicates whether the purchase order was accepted, rejected or if any changes may have been made to the accepted orders by the seller. Just like with most acknowledgement transactions, EDI 855 can indicate that the order was accepted, rejected or accepted with changes, which looks like this:
- Accepted – The purchase order has been accepted.
- Rejected – The purchase order has been rejected.
- Accepted With Changes – Changes were accepted to the purchase order. (3 outcomes)
- All line items are accepted, freight changes or cash terms. (Header Level Changes Only)
- Change or reject one or more line items, no header-level changes would be made.
- Header-level changes and one or more line items have been changed or rejected.
Each one of these acknowledgements could be provided with or without an indication of product availability. The 855 transaction could also be used to communicate pre-arranged merchandise shipments directly from the vendor. The seller will usually transmit an 810 Invoice once the product ships. In some cases, an 856 Advance Shipping Notice (ASN) must be provided prior to the shipment.
