Commonly used EDI signals

EDI 850(Purchase Order)
An EDI 850 Purchase Order is an electronic version of a paper Purchase Order.A buyer will use the 850 Purchase Order to communicate to a supplier the specific items, price, and quantities they wish to have delivered.Each EDI Purchase Order document will have data organized into segments and data elements.Each segment contains at least one data element. Each data element is a data field. Examples of data elements on the Purchase Order include vendor number, item, quantity, price per item, street address, city, state and zip code, just like on a paper purchase order. The standards bodies have allowed for every conceivable possibility for data on the EDI Purchase Order document. Any one company will use a small subset of the available choices within the ANS X.12 or UN/EDIFACT standards

EDI 810(Invoice)
An EDI 810 Invoice is an electronic version of a paper Invoice or bill.A supplier will use the 810 Invoice to communicate to a buyer the specific items, price, and quantities they have delivered and now must be paid for by the buyer. Payment terms will usually accompany the billing information.

EDI 856(Advance Shipping Notice)
An EDI 856 Advance Shipping Notice is an electronic version of a printed packing slip that tells a buyer how a supplier has packed their items for shipment. Most ASNs will follow either standard pack or pick and pack guidelines. Usually the buyer will specify how they want the goods packed. The Advance Ship Notice, or ASN, also tells the buyer that the goods have been shipped so they can be expecting the shipment.The EDI Advance Ship Notice along with the UCC-128 bar code label lets the receiving dock know what is in the supplier’s cartons without having to open the cartons. The UCC-128 bar code label contains the supplier’s vendor number, ASN number, and carton number. The receiving dock can scan the bar code label and then check the EDI ASN that was previously received electronically from the supplier to know the contents of the cartons.

EDI 855(Purchase Order Acknowledgment)
An EDI 855 Purchase Order Acknowledgment is an electronic version of a phone call or fax that tells the buyer who sent you a purchase order that you will be filling the purchase order as requested. The buyer then knows that you will be filling the order and shipping the goods as requested by the date requested.However, if you will not be able to fill the order, then the 855 Purchase Order Acknowledgment is used to tell the buyer that you will not be able to fill the order. You may be out of stock for the items specified or you may not agree with the Purchase Order business terms.

EDI 860(Purchase Order Change Request )
Based on the Accredited Standards Committee (ASC) X12 format, the 860 is used to provide the information required for the customary and established business and industry practices relative to a purchase order change. This transaction can be used by: (1) a buyer to request a change to a previously submitted purchase order; or (2) a buyer to confirm acceptance of a purchase order change initiated by the seller or by mutual agreement of the two parties

EDI 997(Functional Acknowledgment)
An EDI 997 Functional Acknowledgment is an electronic version of a receipt. The Functional acknowledgment tells a sending trading partner that a receiving trading partner has in fact successfully received EDI transactions. For example, when a buyer sends a supplier an 850 Purchase Order, the buyer will want the supplier to send a 997 Functional Acknowledgment back to indicate that the Purchase Order was received.
