Microsoft is releasing a preview of the next version of Power BI Report Server. The new Power BI report Server contains some great new self-service BI capabilities, including support for data sources other than SQL Server Analysis Services and viewing and interacting with Excel Workbooks.
With August 2017 preview, Power BI users can create reports in Power BI Desktop that connect to any data source and publish their reports to Power BI Report Server. This was however restricted to only reports on-premises by connecting to SQL Server Analysis Services data sources, earlier.
Additionally, Power BI users can also view and interact with Excel Workbooks with August 2017 preview update. This will help business analysts to more easily gather, shape, analyze, and visually explore their data in Power BI.
To learn about these and other new features in the August preview, including support for the new table and matrix visuals, make sure you read the release notes.
