Summary:

Buyer to be notified when a requisition is approved

Content (required):

Hi team - we have a requirement that whenever a requisition is approved, a notification should be triggered to the respective buyer saying so and so req is approved.

I have set an approval rule with FYI action in 'Postapproval Header Hierarchy' to Assigned Buyer. But the notification has subject like 'Approve Requisition ****', whereas expectation is that notification should be like 'Requisition **** Approved'(just like the notification that is sent to Preparer whenever a requisition is approved). Is there any way we can achieve this?
