X12 855 Purchase Orders Acknowledgement

The X12 855 transaction set is a Purchase Order Acknowledgement. It is used by sellers to confirm the receipt of a purchase order (an EDI 850 transaction) from a buyer, eliminating the need to call or fax confirmation. The 855 also communicates whether the PO was accepted or rejected, or what changes may have been made to accepted orders by the seller. Thus, like many acknowledgment transactions, the 855 can indicate that the order was accepted, rejected, or accepted with changes, as follows:

• Accepted
• Rejected
• Accepted with Changes
  • All line items accepted, change freight or cash terms (i.e., header level changes only)
  • Change or reject one or more line items, no header-level changes
  • Header-level changes and one or more line items changed or rejected
