How can I set up an approval rule to route a requester-initiated change order to the requisition's overriding approver?

Create an approval rule with a condition to check if the backing requisition has an overriding approver. Also configure the condition to check if the change order is requester-initiated.

In the rule action, you can route the change order approval through the override approver's job levels, supervisor hierarchy, or position hierarchy.

Create the approval rule using the Manage Purchasing Document Approvals task. Find the task in the Setup and Maintenance work area, Procurement offering, Approvals Management functional area.
