Power BI Report Server support shared data source for rdl report. There should be same functionality for pbix report.
The ability to connect to a Shared Data Source for Power BI reports hosted on Power BI Report Server would be a HUGE win! Managing data source Live connections for every report individually as they progress from DEV to TEST to PRE-PROD & PROD environments is a significant short-coming & an annoying hassle, especially when the Shared Data Sources are "right there!" and being used for paginated reports. The ability to wire up a Power BI Report to a shared data source would be a HUGE win for Power BI Report Server.
