  • LASTNONBLANK and FIRSTNONBLANK functions work with any column #dax #powerpivot #ssas #tabular

    During a PowerPivot Workshop course we received an interesting question from a student: “Can I use LASTNONBLANK (and FIRSTNONBLANK) with a column which is not a date column?” The reason is that we introduce LASTNONBLANK in the Advanced Time Intelligence module, because its typical use case is on a date column. However, you can use these functions ...

  • Execute a #DAX Query on #SSAS #Tabular in #Excel

    Apparently Excel does not offer a way to import data in Excel by using a DAX query on Analysis Services. The Data Connection Wizard seems to offers only the ability to create a PivotTable when you connect to Tabular, but not a Table (see the Table option disabled in the next picture). However, the workaround is to create a connection file and ...

  • Linked Table, Reverse Linked Table and Linkback Table in Excel 2013 #powerpivot

    Kasper de Jonge wrote a blog post last year introducing an interesting new feature in Excel 2013: you can write a DAX query that extracts data from the PowerPivot model and returns a table in Excel. Such a table can be used as a Linked table for the same PowerPivot model, creating an interesting opportunity to inject data in a data model mixing ...

  • DATE function does not support all the dates in DAX by design #powerpivot #tabular #dax

    The DATE function in DAX has this simple syntax: DATE( <year>, <month>, <day> ) If you are like me, you never read the BOL notes that says in a clear way that it supports dates beginning with March 1, 1900. In fact, I was wrongly assuming that it would have supported any date that can be represented in a Date data type in Data ...
