What is EDI 860?

The EDI 860 Purchase Order Change Request – Buyer initiated is a type of electronic data interchange transaction set that is used to update and amend a previously sent EDI 850 Purchase Order. The 860 streamlines trading partner communications, so changes can be tracked and made easily. 

This electronic document complies with the ANSI X12 EDI specification.

Benefits of the EDI 860

All EDI documents are securely encrypted in transit, allowing trading partners to send sensitive data safely. Sending an EDI 860 eliminates the human interaction to request changes on the purchase Order (EDI 850). Additionally, the automated nature of EDI 860 helps reduce errors associated with manual retyping and the number of customer service touchpoints.

Reduce manual workload by automating possible changes to orders

Reduced risk of error by avoiding human interaction

Updating of time-critical orders speed up the entire ordering and adjustment process

How is an EDI 860 Used?

A buyer would first create an EDI 850 purchase order to place the initial request to their supplier. Then the EDI 860 can then be used to change or cancel one or more items/goods from the previously sent PO. They are also used to update the supplier with previously unknown details specific to the order, such as;

  • customs changes
  • transport and delivery details

The supplier can then answer with a purchase order acknowledgement EDI 855.
