Credits to AI for the provided solution. Please accept it if you find it helpful. Row-Level Security (RLS) in Power BI is a feature that enables you to restrict data access for users at the row level based on their roles. With RLS, you can define filters within your Power BI dataset to ensure that users only see the data they are authorized to access, enhancing security and personalization. How RLS Works Roles Definition : You define roles and set filters for these roles in Power BI Desktop. Filters are applied to the rows in the tables of your dataset. Assigning Users : After publishing the report to the Power BI service, you assign users or groups to these roles. The assignment can be based on Azure Active Directory (AAD) or other authentication systems. Dynamic or Static Filters : Static RLS : Predefined filters for roles. For example, "Role A" can only view sales data for Region X. Dynamic RLS : Filters are based on the user's login information. For example, employees can only view data for their department using functions like USERNAME() or USERPRINCIPALNAME() . Key Features Controlled Data Access : Users can only view the rows of data they are allowed to access. Scalability : Applicable to multiple users with different access requirements. Ease of Maintenance : Filters can be modified easily in Power BI Desktop without changing the underlying data source. Example Use Case A company has a sales report, and each sales manager should only see data for their region: Define a role named "SalesManager" in Power BI Desktop. Apply a filter like [Region] = USERNAME() in the RLS settings. Assign the "SalesManager" role to appropriate users in the Power BI Service. Setting Up RLS Open your Power BI Desktop file. Navigate to Modeling > Manage Roles . Define a role and specify filter conditions for the tables. Save and publish the report to the Power BI Service. Assign users or groups to the roles in the service. Limitations RLS is not applied when viewing the report in Power BI Desktop (only works in Power BI Service). It is not supported with DirectQuery over live connections to certain data sources (e.g., SSAS/Tabular models managed externally). Not intended for high-security requirements as it is enforced within the Power BI service, not the data source. RLS is crucial for organizations requiring secure and tailored data experiences for their users, ensuring compliance and data integrity.
