Send Notification to Buyer after releasing the PR to place a purchase order.

Hello Experts,

I am looking for your help. Client has release procedure at the PR level but not at PO level, after releasing PR the notification is sent to the buyer automatically.Is there SAP functionality (Workflows) that will auto notify buyers when PR’s get released to their PGroup? is there any way to eliminate the need for emails to be sent to buyers notifying them that there are released PR’s that can be actioned.

Please suggest.

Thanks!
