Allow Admins to Impersonate Users with Dataset Access (Without Workspace Access)

In Power BI Service, workspace admins currently cannot impersonate users who have been granted direct access to a semantic model (dataset) but do not have access to the workspace itself. This limitation makes it difficult to:

• Validate Row-Level Security (RLS) configurations for external or limited-access users.
• Troubleshoot access issues or test user-specific views of data.
• Support delegated administration and governance in large organizations.

Proposed Feature: Enable workspace admins (or users with appropriate permissions) to impersonate or simulate the experience of a user who has direct access to a dataset, even if that user does not have access to the workspace. This could be implemented as:

• A “View As User” option in the Power BI Service, similar to “View As Role” in Power BI Desktop.
• An API endpoint or admin tool that allows simulation of user access for testing purposes.

Benefits:

• Enhances security testing and validation workflows.
• Improves support and troubleshooting capabilities.
• Aligns with enterprise governance and access control needs.
