How to Share Power BI Published Reports with RLS as Public: A Comprehensive Guide
Power BI, Microsoft's flagship business analytics service, offers comprehensive tools for visualizing data and sharing insights across an organization or embedding them in an app or website. Despite its extensive capabilities, many users find themselves stumped when attempting to share published reports with Row-Level Security (RLS) as public. This guide is designed to fill that knowledge gap and provide a clear, actionable process for sharing your Power BI reports with RLS, ensuring that sensitive data remains secure while still being accessible.
Understanding Row-Level Security (RLS) in Power BI
Row-Level Security (RLS) in Power BI enables you to control access to rows in a database table based on the roles assigned to different users. This ensures that users can only see data relevant to them, making it an essential feature for organizations that need to maintain strict data privacy and compliance standards.
Implementing RLS correctly is crucial for safeguarding sensitive information, especially when sharing reports publicly. It allows report developers to create a single report and tailor the visibility of specific data points to different users or groups without the need to create multiple reports.
Step 1: Setting Up Row-Level Security in Power BI Desktop
To implement RLS, start by defining roles and their respective DAX (Data Analysis Expressions) filters within Power BI Desktop.
- Create Roles: In Power BI Desktop, navigate to the 'Modeling' tab, and select 'Manage Roles'. Click 'Create' to start defining a new role.
- Define DAX Filters: For each role, you will need to specify DAX formulas that determine which data the role can access. For example, a formula might restrict data to a specific department.
Repeat this process for each role that requires access to your report.
Step 2: Publish Your Report to Power BI Service
Once you have set up RLS and prepared your report in Power BI Desktop, publish it to the Power BI Service.
- Go to the 'File' menu, and select 'Publish' > 'To Power BI'.
- Sign in to your Power BI account if prompted, and choose the workspace where you want to publish the report.
Step 3: Configuring RLS Settings in Power BI Service
After publishing, you need to configure the RLS settings in the Power BI Service to match those defined in Power BI Desktop.
- Navigate to the dataset settings within your workspace.
- Under 'Security', you will find the roles you created in Power BI Desktop. You can now add members to these roles. Members assigned to a role will only see data permitted by the DAX filters associated with that role.
Step 4: Sharing Your Report Publicly
Sharing a report with RLS enabled requires careful consideration. Power BI doesn’t natively support sharing RLS-protected reports as public links due to the inherent risks of exposing sensitive data. However, there are methods to share your insights while maintaining control over data security:
- Publish to Web: Power BI’s 'Publish to web' option allows you to create a public URL or embed code for your report. However, this method does not respect RLS settings, making it unsuitable for sensitive reports.
- Power BI Embedded: A more secure alternative is to use Power BI Embedded, which supports RLS. This Azure service allows you to embed reports in custom applications, ensuring that RLS is enforced when users access the report.

Best Practices and Considerations
- Always Verify Security Settings: Before sharing any report publicly, thoroughly review your RLS configurations and test the report with different user accounts to ensure that data visibility is correctly restricted.
- Monitor Usage and Access: Regularly audit who has access to your reports and how they're being used to prevent unauthorized access to sensitive data.
- Stay Informed about Policy Changes: Microsoft frequently updates Power BI features and policies. Stay current to ensure your sharing methods comply with the latest security standards.
