Using SSAS Multidimensional As A Data Source For Power BI (Video)

The nice people at PASS have made a video of my session on “Using SSAS MD as a data source for Power BI” available to view for free on YouTube:

I’m honoured that it’s listed one of their “Best of PASS Summit 2017” sessions, and there are lots of other great videos on the same page including Alberto Ferrari’s session on DAX optimisation.

Some of the tips in this video include a few things I’ve been meaning to blog about for a while, including how important it is to set the ValueColumn property on your dimension attributes in SSAS MD – it lets you use lots of functionality in Power BI that isn’t otherwise available, including date slicers.

  1. Great Video! I’ve found more often than not advanced users are importing from SSAS MD. This is occurring mostly due to adding new calcs or the needed to display charts from more than one cube. IT can add more calcs and build bigger cubes, but this in direct conflict with self-service. Your advice to use the Database and query directly isn’t a great option for users that may be more advance with analytics and building report, but not with relational databases. I hope MS continues to develop solutions to allow Power BI and SSAS MD to work together.

    We recently worked with MS to resolve performance issues with importing. There is a second MDX engine which works well with importing large amount of data. The following MCode changes will provide access to the 2.0 engine.
    Source = AnalysisServices.Databases(“cube”, [TypedMeasureColumns=true, Implementation = “2.0”])

    • Interesting – I hadn’t heard about the Implementation = “2.0” option, I’ll have to check it out.

      The Live Connection/Import decision will depend a lot on how well your cubes are designed in the first place. If your users need to build charts from more than one cube it sounds like someone has made a bad design decision somewhere along the line, and probably should have built one cube rather than several. I understand the point you’re making though.

    • @Rayishome,
      I came across with the Implementation property when developing Tabular model in 1400 compatibility mode – and the property added for SSAS Tabular data source. However, I am not able to find more about the property in MSDN site too.
