DAX Measure Dependencies in SSAS Tabular and Power BI

21-01-2019  0 Comment(s)

DAX measures are the heart of every SSAS Tabular model, Power BI and Power Pivot solution. You write lots of DAX measures and you potentially reference some of them in other measures. So the number of DAX measures you write and reference them via other measures grow very quickly. Especially in complex solutions you may have hundreds of DAX measures. While your solution works perfectly, to make a minor change or adding a new measure to the solution or fixing a problem in your existing measures can be such a pain in the neck. In this post I’m going to take a step further and show you a simple way to get the whole data model dependencies then visualise the dependencies in Power BI. You can find the download link at the end of this post.

An easy way, after you find the local port number of an opened Power BI Desktop file, is to find the database name from SQL Server Management Studio (SSMS) when connecting to the Power BI Desktop model:

  • Open SSMS
  • Select “Analysis Services” as “Server Type”
  • Type in “localhost:PORT_NUMBER” as “Server Name” then click “Connect”

 

Getting Tabular Model Object Dependencies Data from SSAS Tabular

  • Open Power BI Desktop
  • Select “SQL Server Analysis Services database” then click “Connect”
  • Enter the “Server” and “Database”
  • Make sure you select the “Import” mode
  • Expand “MDX or DAX Query” and copy/paste the following DMV then click OK
