You need to create a secure way for external business partners to access specific reports in your Fabric workspace, without giving them access to the underlying data or other workspace items. What…

Sharing the entire workspace, even with a Viewer role, would grant partners visibility into all items within the workspace (reports, semantic models, dataflows, etc.), which goes against the requirement of limiting access to specific reports only.

Creating a Power BI app that bundles the specific reports and then sharing this app with external business partners is the most secure and controlled method. Power BI apps provide a curated experience, allowing partners to view only the included reports and dashboards without direct access to the underlying semantic models, other workspace items, or the entire workspace itself.

Exporting reports to PDF and emailing them is a manual, non-real-time, and insecure method for ongoing access. It lacks interactivity, auditability, and scalability for managing access to multiple reports or many users.

Granting direct read permissions to specific reports might still expose some metadata or path to the underlying semantic model, or it might not provide the same level of isolation and curated experience as a Power BI app, especially when considering external users.
