When implementing row-level security (RLS), Power BI developers should define user roles and create filters that limit data visibility based on those roles. Use a central security table to manage access, making it easier to scale and maintain RLS policies. Test the RLS configuration thoroughly to ensure that users only see data relevant to their roles. Power BI developer should also document security rules and keep track of user access rights to simplify future updates. RLS ensures that sensitive data is protected, especially in shared reports across teams or departments.
