Learn about what data sources you can connect to within Power BI Report Server.
Currently, the only data source supported for Power BI reports are a live connection to Analysis Services (tabular or multidimensional). More data sources will be added in future releases.
If you try to publish a Power BI Desktop file that contains anything other than an Analysis Services live connection, you will see the following error.
Can't upload this report We can’t open this Power BI report because it contains an unsupported data source connection or embedded data. This version of Power BI Report Server supports Power BI reports that connect live to SQL Server Analysis Services or Azure Analysis Services.
Other report types support the same data sources that are present in SQL Server Reporting Services. For more information, see Data sources supported by Reporting Services.
