I’ve been playing about with PowerView and PowerPivot recently, while also getting used to the Analysis Services (SSAS) Tabular model in SQL Server 2012 (Denali). The tabular model provides a high-compression, in-memory store for easy data model construction and analysis. Ad-hoc calculated fields can be defined within PowerPivot (built on the same xVelocity technology) using Microsoft’s Data Analysis eXpressions language, which is very similar to Excel functions. However, DAX is still pretty basic in some places, and while looking for a simple Month Name function (similar to the GetMonthName function in .NET) I ran into a couple of interesting issues.

So, you’ve finally got around to setting up that SQL Server 2012 environment and you’re playing about with PowerPivot and SQL Server Analysis Services. You’ve set up your sharepoint site and you’ve created and uploaded a new spreadsheet using PowerPivot that contains all that tasty cube data. However, in your haste, you haven’t set up SQL Server Reporting Services Report Builder on the Sharepoint site, so when you open Report Builder on a separate server (or from a local install), and want to connect into your new quasi-cube (via your PowerPivot Excel file), how do you do it? The Report Builder side of things is not too dissimilar to using a traditional SSAS cube as a Data Source.
The answer, is deceptively simple if you know where to look. Continue reading “How To Connect SSRS Report Builder to a PowerPivot Excel file (Sharepoint)” »
