How can I restrict access to certain Reference Data Set?

We Require to secure the access to all objects in a specific reference data set

Hello community,

Due to security policies, we are trying to secure access to jobs, locations, and grades. We are using a unique data set per business unit.

Under these conditions, some users should only see the structure of their own business unit; We are using an organization-specific profile to achieve this. However, this doesn't prevent a user from seeing definitions of other business units.

Can someone tell me how the security I mentioned is possible?

Regards.
