Refer to a parameter for Comma-Separated Values data source

Hi Everyone,

 

I cannot find a way to refer a parameter to the file path parts.

Is there any way to do this? Or Power BI Desktop Developer has oversight of this.

 

Need Help

    Have you tried the Advance Editor and adding a parameter directly to the M code?

      How to add in Parameter in the Advance Editor? I have tried to put just the name of the parameter but it failed.

       

      Thanks

        I created a parameter in the Query Editor.  I called it myParameter and set it to TEXT with a value of c:\temp\a.csv

         

        I then edited the M code via the Advanced Editor and made the change in red.  Note all text is case sensitive

         

        let
    Source = Csv.Document(File.Contents(myParameter),[Delimiter=",", Encoding=1252])
in
    Source

        I could then change the value for the parameter in the query editor to say, c:\temp\b.csv and when I refresh I see the contents of the new file.

         

        Does that help?  I can send a sample PBIX file if you like.
