Power BI does not offer a direct way to block users from publishing reports to their personal workspace, but this can be managed through a combination of governance policies and permission settings. To control where reports connected to sensitive data sources like Azure SQL Database are published, organizations should restrict access to personal workspaces by using Microsoft 365 security groups and enforce role-based access to organizational workspaces.
Additionally, using managed permissions within Power BI Apps allows administrators to publish a single version of a report and share it with multiple audience groups while keeping tight control over who sees what. This approach not only ensures data governance but also enhances report distribution efficiency and compliance. For more structured access, consider adopting the “Apps for Multiple Audiences” model, which allows precise permission control across different user groups without duplicating content.
