Acknowledgement Change Approval
If the supplier makes changes to a purchase order that exceed the tolerance, the system sends a workflow message to the buyer's work center. The Acknowledgement Approval queue in the work center contains all of the orders that have failed the tolerance test and are waiting for the buyer to review and approve them.
The workflow message contains a link that enables the buyer to launch the Approve Purchase Order page in the Collaborative Portal. From this page, the buyer can approve or reject the supplier's changes. The buyer can also attach a text note or attachment that is included in the approval or rejection message that is sent back to the supplier.
When the buyer clicks either Approve or Reject on the Approve Purchase Order page, the system sends a workflow message to the supplier in either the Acknowledgement Approved or Acknowledgement Rejected work center queue.
