October 2017 release

Power BI report data sources

Power BI reports in Power BI Report Server can connect to a variety of data sources. You can import data and schedule data refresh, or query it directly using DirectQuery or a live connection to SQL Server Analysis Services. See the list of data sources that support scheduled refresh and those that support DirectQuery in "Power BI report data sources in Power BI Report Server".

Scheduled data refresh for imported data

In Power BI Report Server, you can set up scheduled data refresh to keep data up to date in Power BI reports with an embedded model rather than a live connection or DirectQuery. With an embedded model you import the data, so it's disconnected from the original data source. It needs to be updated to keep the data fresh, and scheduled refresh is the way to do that. Read more about "scheduled refresh for Power BI reports in Power BI Report Server".

Editing Power BI reports from the server

You can open and edit Power BI report (.pbix) files from the server, but you get back the original file you uploaded. This means if the data has been refreshed by the server, the data won’t be refreshed when you first open the file. You need to manually refresh it locally to see the change.

Large file upload/download

You can upload files up to 2 GB in size, though by default this limit is set to 1 GB in the Report Server settings in SQL Server Management Studio (SSMS). These files are stored in the database just as they are for SharePoint, and no special configuration for the SQL Server catalog is required.

Accessing shared datasets as OData feeds

You can access shared datasets from Power BI Desktop with an OData feed. For more information, see Accessing shared datasets as OData feeds in Power BI Report Server.


This release supports scale-out. Use a load-balancer and set server affinity for the best experience. Note that the scenario is not yet optimized for scale-out, so you'll see models potentially replicated across multiple nodes. The scenario will work without the Network Load Balancer and sticky sessions. However, you'll not only see an over-use of memory across nodes as the model is loaded N times, but performance will slow in between connections as the model is streamed as it hits a new node in between requests.

Administrator settings

Administrators can set the following properties in SSMS Advanced Properties for the server farm:

  • EnableCustomVisuals: True/False
  • EnablePowerBIReportEmbeddedModels: True/False
  • EnablePowerBIReportExportData: True/False
  • MaxFileSizeMb: Default is now 1000
  • ModelCleanupCycleMinutes: How often it checks to evict models from memory
  • ModelExpirationMinutes: How long until model expires and is evicted, based on last time used
  • ScheduleRefreshTimeoutMinutes: How long data refresh can take for a model. By default, this is two hours. There is no hard upper limit.

Developer API

The developer API (REST API) introduced for SSRS 2017 has been extended for Power BI Report Server to work with both Excel files and .pbix files. One potential use case is to programmatically download files from the server, refresh them, and then republish them. This is the only way to refresh Excel workbooks with PowerPivot models, for example.

Note that there is a new separate API for large files, which will be updated in the Power BI Report Server version of Swagger.

SQL Server Analysis Services (SSAS) and the Power BI Report Server memory footprint

Power BI Report Server now hosts SQL Server Analysis Services (SSAS) internally. This isn't specific to scheduled refresh. Hosting SSAS can greatly expand the report server memory footprint. The AS.ini configuration file is available on the server nodes, so if you're familiar with SSAS, you may want to update the settings, including maximum memory limit and disk caching etc. See Server properties in Analysis Services for details.

Viewing and interacting with Excel workbooks

Excel and Power BI contain a portfolio of tools that is unique in the industry. Together, they enable business analysts to more easily gather, shape, analyze, and visually explore their data. In addition to viewing Power BI reports in the web portal, business users can now do the same with Excel workbooks in Power BI Report Server, giving them a single location to publish and view their self-service Microsoft BI content.

We’ve published a walkthrough of how to add Office Online Server (OOS) to your Power BI Report Server preview environment. Customers with a Volume Licensing account can download OOS from the Volume License Servicing Center at no cost and will have view-only functionality. Once configured, users can view and interact with Excel workbooks that:

  • Have no external data source dependencies
  • Have a live connection to an external SQL Server Analysis Services data source
  • Have a PowerPivot data model

Support for new table and matrix visuals

Power BI Report Server now supports the new Power BI table and matrix visuals. To create reports with these visuals, you will need an updated Power BI Desktop release for the October 2017 release. It can't be installed side-by-side with the Power BI Desktop (June 2017) release. For the latest version of Power BI Desktop, on the Power BI Report Server download page, select Advanced download options.
