You have multiple Power BI workspaces with datasets that connect to the same on-premises SQL Server database. Users report inconsistent data across reports. You need to implement a solution that ensures all reports use the same data while minimizing refresh times and maintenance. What should you do?

You need to implement a solution where regional managers can only see data for their respective regions in all reports within a workspace. The solution must be maintainable as managers are added or removed frequently. The Region table has a column named RegionName, and user information is stored in Azure Active Directory with a custom attribute called AssignedRegion. What should you implement?
