Microsoft today made available the August 2017 preview of Power BI ReportServer 2017. This preview includes the long awaited support of embedded data models, as well as the ability to render Excel reports natively. This is a major step forward, because with this release, Microsoft has completed its vision for its on-premises reporting platform that it first articulated in October of 2015.
Excel content being rendered in Power BI Reporting Server
The big news at the time was that the platform was stated to be SQL Server Reporting Services (SSRS). Not SharePoint, not PerformancePoint, but SSRS. SSRS was a mature product that quite competently provided a platform for operational reports. What it needed was some modernization and the addition of some analytical and self-service reporting capabilities. Several of these capabilities were subsequently included with the release of SSRS 2016.
Gone would be the days of configuring complex SharePoint farms just to be able to work with analytical reports (ie Power View, Excel). New Features were being added to SSRS to make it a complete platform for both analytical and operational reports.
The roadmap articulated four different report types, 3 of them analytical (by my definition) and one of them operational. These three types line up with reporting tools in the Microsoft BI stack:
|Name||Type||Primary authoring tool||ext|
|Paginated||Operational||SSRS Report Builder
SQL Server Data Tools
|Interactive||Analytical||Power BI Desktop||.PBIX|
|Mobile||Analytical||Mobile Report Designer||.RDLX|
Therefore, reading between the lines, in order to be a complete reporting platform, SSRS needed to be able to render all of these report types. Paginated reports were of course always native to SSRS, and the roadmap announced that Mobile reports would be included in SSRS 2016 through the integration of Datazen. The roadmap further committed to SSRS being able to render Power BI files in the future.
SSRS shipped with some significant modernization improvements, including a much awaited HTML5 rendering engine, and it included Mobile Reports. Mobile reports are delivered through the Power BI mobile application, and SSRS visuals can be pinned to Power BI dashboards.
Significant plumbing was done to move the platform forward in 2016, but it still only rendered 2 of the 4 report types.
In November 2016, it was further announced that the 2016 version of SSRS running in SharePoint Integrated mode would be the last. Moving forward, Reporting Services will only run in Native Mode. In the same announcement. In the same announcement, as I noted in another post, for the first time, the SSRS team committed to providing Excel report rendering capability as well.
Power BI Reporting Server
We first saw the on premises rendering of Power BI reports in the first community preview of SSRS V.Next in the fall of 2016. Those previews required that the reports be directly connected to SSAS tabular models, but they were ground-breaking just the same. A user could be totally disconnected from the web, and still render Power BI reports.
In May of 2017, Power BI Report Server (PBIRS) was announced. A less confusing name could have potentially been SSRS Premium, because that is in essence what it is. PBIRS is everything that SSRS is, plus the ability to render Power BI reports. SSRS will continue forward as a product without Power BI rendering capabilities. It is just a licensing distinction.
The release today of the August 2017 preview of PBIRS allows for embedded data models, and therefore a much wider breadth of capabilities. These models cannot be automatically refreshed yet, but they will upon release. This is, after all, just a preview. If you need automatic refresh of these data models in the meantime, there is an excellent third party solution to do this: PowerPivot Pro’s Power Update.
The inclusion of Excel report rendering capabilities means that PBIRS is a complete report rendering platform, more complete even that the Power BI cloud service.
Now that the basic on-premises capability has been provided, SSRS/PBIRS needs to pay attention to paying back the debt that it incurred when SharePoint Integrated mode was deprecated. Chief among these features is the SSRS web part. The lack of a decent web part is a blocker for many organizations to move forward with this strategy. Some migration tools to move from Integrated to Native mode (like this one that migrates in the other direction) would be highly useful as well.
Now with on-premises covering all the bases, it’s easy to spot a glaring hole in the cloud Power BI offering. While it supports all three types of analytical reports, there is currently no way to render operational reports in the cloud. Until this capability is provided, it appears that on-premises will have the most complete solution.
