This Draft Standard for Trial Use contains the format and establishes the data contents of the Purchase Order Acknowledgment Transaction Set (855) for use within the context of an Electronic Data Interchange (EDI) environment. The transaction set can be used to provide for customary and established business and industry practice relative to a seller's acknowledgment of a buyer's purchase order. This transaction set can also be used as notification of a vendor generated order. This usage advises a buyer that a vendor has or will ship merchandise as prearranged in their partnership.
How is an EDI 855 used?
For example, after Retailer A sends an EDI 850 Purchase Order to Vendor B, Vendor B will respond with an EDI 855 Purchase Order Acknowledgment. It contains details about whether the order can be fulfilled fully, partially, or not at all. If the order is able to be shipped, an EDI 856 Ship Notice/Manifest and EDI 810 Invoice will likely follow.
