Purchase Order Acknowlegement B2B 855 Price Change Functionality

Summary:

Our business is working with multiple vendors to set up Purchase Order EDI communications. We currently have some vendors provide an 855, order acknowledgement but they simply acknowledge receipt and do not perform any edits.

A newer vendor is interested in initiating edits such as price changes. In reading this document, linePriceChange code can be set up, however the expected result is not clear.

Content (please ensure you mask any confidential information):

For other supplier initiated edits, such as line changes, the documentation clearly calls out that supplier
initiated change order is created.

For line price changes, would this initiate a change order for the buyer to review and approve? Or would this automatically update the price on the PO line without a change order? If it is the latter, would the buyer have clear visibility to the change such as an entry into the PO revision/change order history?
