Summary:

Supplier Acknowledgement for PO Line Close/Reopen Status Changes in Oracle Fusion

Content (please ensure you mask any confidential information):

We have a customer who plans to enable the Purchase Order Acknowledgment feature in Oracle Fusion Purchasing.

Currently, we understand that supplier acknowledgement is required before a PO becomes Open and when a PO Change Order is issued.
In addition, we are aware that Oracle Fusion supports supplier acknowledgement when a PO line status is changed to Cancelled.

However, the customer has an additional requirement. They believe that changes to PO line statuses should also require supplier acknowledgement, not only for cancellation.
