We would like to avoid to share Subject Areas between Answers and Dataviz for users accessing to both tools.

We have two groups :

Group A : BI Content Author

Group B : DV Content Author

We have also two domains :

Subject Area 1 (Big DataWareHouse)

Subject Area 2 (Small Datamart)

And we need specific access on :

Answers

Dataviz

We gave privileges to Subject Area 1 for BI Content Author and Subject Area 2 for DV Content Author

Now :

If a user from Group A connect on Answers he will see Subject Area 1

If a user from Group B connect on Dataviz he will see Subject Area 2

My idea:

Avoid an user belonging to both groups to see Subject Area 2 on Answers and Subject Area 1 on Dataviz

Maybe if we can give privileges specifically to Answers and to Dataviz could we avoid in Dataviz to see Subject Area 1 for all users and avoid in Answers to see Subject Area 2 for all users
