You can assign a user to multiple roles. When a user has more than one role, the role access permissions are cumulative, meaning that the user's resulting access is the sum total of each individual role.
For example, user sam is assigned to the roles User Access Administrator, Data Source Administrator, and Business Glossary Administrator. The user sam gets the permissions that have the least restricted access.
Note: Your software license determines user-based entitlement. Contact your sales representative if you have questions about this feature.
