Notification email when selecting determinated category

I´m working on SAP Solution Manager 7.1 and I am trying to create this scenario:

While creatiing or after saving a new message (indicent or service request) I want to detect the category selected in a multilevel categorization schema.

At this point, when the determinated category is selected, i would like to notify by email to one or several business partners.

Is it possible to configure it?

Thanks in advance.

Note: If a new message is created with category ZMIN_REQ_PRJ_ I want to send a notification email to a business partner.

Best regards
