Row Level Security and Mobile View Report?

Hey Jarek,

Power BI Mobile apps respect RLS - so your users should get only the data they have permission to view.

For you technitians, you can create phone report layout (https://docs.microsoft.com/en-us/power-bi/mobile-apps-view-phone-report ) for the same report you have for the managers. Phone report layout is optimized for mobile device consumption and you can place on the phone layout only the visuals that are relevant for the technicians. once you have a phone report, when the technicians will access this report page from their mobile phone they will get different layout than the managers. 

There is a current limitation that visuals in your phone report layout must be a subset of those visuals that are in the landscape reports (the report for managers shown on the browser), so if you need the technitians report to have visual that you don't need in the managers view, you still need to create and place it in the manager's view behind another visual and allocate it very small canvas size.

Hope it address your needs,

Maya
