Filter One Dashboard from Another Dashboard

If you are really talking about Power BI Dashboards, ie collection of tiles, then i dont think you can do that.

But if you are actually referring to Power BI Reports, the only option that im aware of to transfer a selection (filter context) from one report to another is currently by using cross-report drillthrough

Hi AllianceDA ,

Thanks for Tutu_in_YYC reply, that's really helpful!

AllianceDA Based on my tests, PowerBI does not allow queries from one dashboard to affect the other because each sends a different query to the data source. One way I can think of is to create a main menu interface that customers can only switch to if they are authorized to do so. In addition, using a Row-level Security  for data, customers can only see the records that are relevant to them.

Different pages for managers and customers: Customer can only select customer page and navigate to customer page.
