  • DIVIDE vs division operator in #dax

    Alberto Ferrari wrote an interesting article about DIVIDE performance in DAX. This new function has been introduced in SQL Server Analysis Services 2012 SP1, so it is available also in Excel 2013 (which still doesn’t have other features/fixes introduced by following Cumulative Updates…). The idea that instead of writing: IF ( Sales[Quantity] ...

  • Calculate New, Returning, Lost, and Recovered Customers in #dax

    Calculating the number of new and returning customers is a recurring question. I would say this is a “classical” Business Intelligence problem, very common in marketing department. I worked on these problems with many customers, with small and large datasets, and I wrote a DAX Pattern “New and Returning Customers” showing how to calculate: New ...

  • Connecting to #powerpivot from an external program (such as #Tableau)

    Many people requested me how to connect to Power Pivot from an external program, without publishing the workbook on SharePoint or on Analysis Services Tabular. I always said it is not possible (for both technical and licensing reasons), but someone observed that Tableau is able to extract data from a Power Pivot data model connecting directly to ...

  • Using Added Columns in #DAX Queries

    I had an issue in a query that reminded me a few details naming columns created by ADDCOLUMNS. When you specify a simple name in ADDCOLUMNS, you can use it later, for example in a SUMMARIZE or in a FILTER expression, such as in the following example (see the Value column): EVALUATE CALCULATETABLE (     ADDCOLUMNS ( ...

  • Power Query now imports relationships #powerquery #powerpivot

    The December release of Power Query preview (version 2.9.3502.261) introduced an interesting feature: when you import multiple tables in the data model, relationships existing between tables in the data source are automatically detected and added to the data model as well. This is similar to the behavior you have in Power Pivot, but there is an ...

  • Dynamic Calculation of Inventory with #dax in #powerpivot and #ssas #tabular

    I recently wrote an article on SQLBI describing the dynamic calculation of stock inventory in DAX. With this technique, you can avoid creating a snapshot fact table just to store the inventory stock for every day and every product, creating a table that in certain business is huge and expensive, especially if you have to load it in memory. I also ...

  • DAX Studio for Excel 2013 finally available! #dax #excel #powerpivot #ssas #tabular

    I'm so happy that DAX Studio finally supports Excel 2013! As Darren Gosbell described in his blog, this release has a few internal changes that will better support future enhancements. I will port the code to capture the query plan for a query in this new release, but unfortunately it will require some weeks because I'm traveling a lot in these ...

  • PowerPivot Workbook Size Optimizer #powerpivot #tabular

    Microsoft released the Workbook Size Optimizer for Excel, the first version of an Excel add-in for Excel 2013 that inspects the data model and suggest possible optimizations. Fundamentally, it tries to apply the best practices descripted in a white paper I mentioned a few weeks ago, removing useless columns and changing granularity to those that ...
