Row-Level Security (RLS) in Power BI allows you to restrict data access for specific users based on their roles. It ensures that users see only the data they are authorized to view, which is crucial for maintaining confidentiality and compliance.
RLS is commonly used in scenarios like regional sales reporting, HR dashboards, or financial reports where different users need access to different subsets of data.
How Row-Level Security Works
- RLS uses roles with DAX filters to define which rows a user can see
- Users are assigned to roles either in Power BI Desktop or Power BI Service
- When a report is published, Power BI automatically applies the security rules for each user
Steps to Implement RLS
Step 1: Define Roles in Power BI Desktop
- Go to Modeling → Manage Roles
- Click Create to define a new role
- Apply a DAX filter on a table to restrict rows
Example – Regional Sales Role
[Region] = "North"
- Users assigned to this role will only see data for the North region
Step 2: Test Roles
- Click View As → Other Roles in Power BI Desktop
- Select the role to see how the report appears for users in that role
- Ensure all visuals and filters respect the role restrictions
Step 3: Publish Report
- Publish the report to Power BI Service
- Navigate to the dataset → Security
- Assign users or groups to the roles you created
Step 4: Maintain and Update Roles
- Update roles when new users or additional regions are added
- Test roles regularly to ensure proper access
Example Scenario
- A company has sales data for North, South, East, and West regions
- Define roles:
NorthRole,SouthRole,EastRole,WestRole - Assign users to their respective regional roles
- Each user sees only their region’s sales when viewing the report
Best Practices
- Keep roles simple and meaningful
- Use AD groups or distribution lists for easier user management
- Test roles thoroughly in Power BI Desktop before publishing
- Combine RLS with workspace permissions for additional security
- Document role definitions and user assignments for compliance
Conclusion
Row-Level Security in Power BI is a powerful feature for data governance and secure reporting. By defining roles and filters, you can ensure that sensitive data is only visible to authorized users, supporting both security and personalized reporting experiences.
