MRP Exception Message Notification

Dear Community,

For the implementation of the MRP Exception Messages,we used this very user friendly post: https://blogs.sap.com/?p=676

We saw all notification were send out to the team members defined in the 'Manage Teams and Responsibilities' app (as expected).

Now we want to send out exception messages with different 'Planning Segment' to different people.
To be able to do so, we saw two possibilities:

Add this 'Planning Segment' to the 'Responsibility Definition in the 'Manage Teams and Responsibilities' app.

Select the relevant team under the 'Recipients' in the 'Manage Situation Types' app. (now all teams are displayed here)

Both are not possible.

Do you have any idea on how to differentiate these notifications and only send them to the relevant users?

Thank you,
Kind regards,
Jonas
