How to run dynamic management view queries within dataflows

[innocence84]

Hi all,

I want to find dataset sizes and saved them into tables via dataflows. I found this URL: https://learn.microsoft.com/en-us/power-bi/enterprise/service-premium-large-models

 

I created a new dataflow and run the query via Azure Analysis Services connection:

let
  Source = #"Dictionary Size Query",
  #"Drill down" = Source{0}[Value],
  Custom = AnalysisServices.Database(#"Workspace URL", #"Dataset Name", [Query = #"Drill down"])
in
  Custom

Then I exported the dataflow. When I try to import the dataflow, I got the below when exception:

How can I run dynamic management view queries for Power BI assets (datasets etc) within dataflows?

 

Thanks
