How can we improve Power BI?

Make functions refreshable when the data source is a parameter of the function

Like discussed here: - queries where data access happens inside a function and where the data source is dependent on parameters to the function should be refreshable.

    I had to take my code out of the function and into the body of Power Query code itself. Kind of messy. Would like to use functions.

    I Need this too, asap

    I dont understand how other users can work without this feature, when tables have Millions of entries and only one day/month/year is important...

    Why is it so difficult, to give a User-Prompt for Parameters, when need

    Any update here? Potential workarounds for parameterized ODBC DSNs?

    Pleaseeee add this Power BI team. I have a list of parameters that my team keeps updated in Google Sheets as that is their preferred method, but I can't refresh pulling from this external source. Need this data to make my API calls in Power BI.

    Just a thought, I wonder if DataFlows would get around this limitation? But is oData supported in DataFlows just yet?

    Any updates on this? Having M work in desktop but not in the service is a real headache; getting this fixed would really help with keeping report development/publishing a more seamless process.

    This thread is three and a half years old...are there any plans to implement this? Not offering this functionality in the online refresh is essentially punishing users for trying to keep their queries and M code neat and organized with functions.

    Just published a report that used this functionality...only to find it isn't there. Hope you guys can make this work at some point.

    Please add this functionality, we would need it for our project =(

  • Redmond Hartop commented  ·   ·  Flag as inappropriate

    More needs to be done to iron out the discrepancies in the execution of desktop and service M code. This idea highlights this need. In the meantime this blog:
    provides a useful workaround to automating some uses of functions and parameters. You may find though that switching the argument 'Query' for 'RelativePath' is more effective for your project.

    I tried building a refreshable M Query using Datachant's iterative function here: and Chris Webb's method to trick the Web.Contents() static analysis of the URL here: BUT this combo doesn't seem to work. Any modification to the Web.Contents() text string that's passed into the function breaks the GeneratedList function. HELP!

    would really need this functionality in order to make my report work

  • Thomas Krekling commented  ·   ·  Flag as inappropriate

    I have a parameter based report, refresh works on it. I have connected the report through my own developed web api. Using a azure app function proxy. The report refreshes nightly after uploading to powerbi cloud

    yes it gwould be very useful. I'm getting a lot the "You can't schedule refresh for this dataset because" error
