Buyer receives email notifications for address and contact change requests by vendors

Hi,

We are implementing iSupplier portal.

We have a separate supplier management group who handles supplier records.

For any changes on supplier address or supplier contacts, our buyer is receiving notifications.

we only want the email id which is set up at the below navigation to be notified.

Purchasing Super User > Setup > Profile Management Configuration > Setup Notification Subscription

Please advice, how can this be achieved.

thank you,

Daniela
