This Draft Standard for Trial Use contains the format and establishes the data contents of the Purchase Order Transaction Set (850) 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 the placement of purchase orders for goods and services. This transaction set should not be used to convey purchase order changes or purchase order acknowledgment information.
What is the EDI 850
An EDI 850 Purchase Order communicates order details from a buyer to a supplier. It contains information about the order identification (BEG Segment), the item details (PO1 segment) and the shipping details (TD5 segment).
How is the EDI 850 used?
For example, Retailer A sends an 850 Purchase Order to Vendor B. Vendor B is then responsible for “fulfilling” that order back to Retailer A. Vendor B will respond with an 855 Purchase Order Acknowledgement to accept or reject the 850 Purchase Order.
To specify the data for scheduling a specific line-item
The SCH segment is used to specify various quantities of items ordered that are to be scheduled. When this segment is used the unit of measurement code (SCH02) should always be identical to the unit of measurement code in the associated PO1 segment (PO103) and the sum of values of quantity (SCH01) should always equal the quantity ordered (PO102) in the PO1 segment.
