How can I route a requester-initiated change order for approval to the requisition's overriding approver?

When you use the Purchase Requisitions work area to create a requisition, you can specify an override approver to replace the first approver.

Your organization can also set up an approval rule to route any subsequent requester-initiated change orders to the same override approver. This ensures your override approver is also able to approve any changes you initiate after the requisition is processed into a purchase order.
