Forward approved requisition notification to Buyer

Hi All,

When a requisition is approved by an approver, a notification goes to requisition preparer stating that requisition has been approved. Can we forward this notification automatically to a buyer?

There is a provision to add the buyer name on requisition lines. Can system pickup this buyer name and forward the approved notification to him/her?

Does it require a full fledged customization? Can we achieve it without customization?

Thanks,

VB
