Row-Level Security (RLS) vs Object-Level Security (OLS) in Power BI Power BI provides robust security features that allow organizations to control data access at various levels. Two key mechanisms for securing data in Power BI are Row-Level Security (RLS) and Object-Level Security (OLS) . 1. Row-Level Security (RLS) What is RLS? RLS restricts access to data at the row level based on user roles. This ensures that users see only the data they are authorized to view without creating multiple reports for different audiences. Implementing RLS in Power BI 🔹 Static RLS – Manually assign user roles and filter specific data. 🔹 Dynamic RLS – Uses a security table with usernames mapped to their respective access levels. Steps to Set Up RLS in Power BI Desktop Create Roles : In Modeling → Manage Roles , define filtering conditions using DAX expressions . Example: Assign Users : In the Power BI Service , assign users to the created roles. Test Security : Use View as Role to verify if access...
