LionelR Can you just connect to the cube, suck in everything and then go back and filter that table in your query for that table? Use the default navigator and select everything instead of using advanced to enter your own DAX.

Hi Greg,

 

Thanks for your response! I have tried this already and successfully created a report in Power Bi desktop, but having issues publishing due to gateway error.

 

 

 

hence, I want to import the data with specific filter criteria and be able to extract data using DAX spanning across different linked tables in the model 

 

thanks for your help!

    HI LionelR,

    >>Thanks for your response! I have tried this already and successfully created a report in Power Bi desktop, but having issues publishing due to gateway error.

    I guess it would relate to power bi security and privacy.
    When you working on desktop side, it has enough permission to process these functions; when you publish to power bi service side, obviously you do not have full permissions to process these queries host on power bi service. Some of the functions will be blocked due to security reasons. (this also apply to other types of script and codes such as r script, python that host in your report)

    LionelR - Odd, I know it's possible to import data from cubes: https://radacad.com/add-or-edit-columns-when-importing-data-from-analysis-services-into-power-bi

      Hi Greg,

       

      Thanks for your response!

       

      I am working out how to restrict data using DAX while importing, to a specific value in a field in a model with multiple tables.

       

      Do you know if I could use a different syntax? the above formula restricts and only shows data from a single table and other data from linked tables are lost.

       

      Thanks

        LionelR - No, but you could create a new query for the other table and then use the table you imported in order to either do a Merge or filter the new table coming in, effectively accomplishing what you want, I *think*. If I understand correctly, you want to import this table within only the rows you want and then have the other related tables also have only the rows that correspond with the rows in this first table that you are importing. Right?
