Add requester and buyer to PO communication email

Hi,

We need to add the requester and buyer as additional recipients/CC when a Purchase Order is communicated by email to the supplier contact.

I checked the following places and couldn’t find where to configure it:

• BPM
• The purchase order page
• Supplier setup
• Configure Procurement Business Function

Is there a standard setup in Oracle Fusion Procurement to add the requester/buyer to the PO communication email, or does this require customization/development?

Thanks
