What is an EDI 855?

An EDI 855 Purchase Order Acknowledgment communicates Purchase Order response details from a supplier to a buyer. It contains information about item availability (LIN Segment), order ship dates (DTM Segment), and replenishment dates for out of stock items (LDT Segment).

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.
