Restrict custom measure group access to custom role(specific users)

Hello,

We also are trying to achieve the same functionality but not seeing expected result:

Steps to Reproduce:

1. Created custom measure group and assigned custom measures to the group
2. Created custom job role copied from seeded demand planner job role and assigned to one user(BRAGULA)
3. Created Data access set in Administer planning security and assigned to custom job role and added custom measure group

Expected result:

1. User BRAGULA should have access to all the seeded tables/layouts/measures including the custom measure group
2. Rest of the users should have access to all the seeded tables/layouts/measures excluding the custom measure group
