    By default , it is not possible.

     

    Alternative way exists:

    a) There is one more way, that you can launch Tabular Editor "TE" and change.

         TE, an external tool you have to install. https://tabulareditor.com/downloads

          Download the free version. You dont need to buy the latest version for this.

     

    b) Once you have Tabular Editor installed, open .pbix file, launch tabular editor.

     

    c) Navigate on the left to the column of the table.

    Say, Delete Summary table, Source.Name is the key column you want to configure.

     

    d) Properties window will show up.

    Set the  "Key"  as "True"

     

    Save and close the TE. You are good to go!

     

    e) In the model view, you will see the key is set.

     

    FYI, By doing this, you can see in the diagram pane and rows selection as key column. But not in the properties window. May be intentional feature by Microsoft team or a bug 🙂 

     

     

     

     

    Hope this helps!

     

    Note: PBI is nothing but SSAS tabular enhanced version.

As far as I'm aware, you can't define a key column for a calculated table. An alternative solution could be to either create the table in the source of your data or to create the table using Power Query. With either of these solutions, you can add in a key column.

oh no 😞 I was hoping there's some other way, I only know dax to create tables, not good at M  language 😞 

 I need to create a summary table from another table, is there an easy way to create this table in power query? 

Projects Summary = SUMMARIZE('Portfolio Reporting','Portfolio Reporting'[Project],'Portfolio Reporting'[Expense Type], 'Portfolio Reporting'[Date],"Actuals",CALCULATE(sum('Portfolio Reporting'[Value]),'Portfolio Reporting'[Versions] IN { "Actuals" }),"Current Budget", CALCULATE(SUM('Portfolio Reporting'[Value]),'Portfolio Reporting'[Versions] IN { "Current Budget" }),"Current Forecast",CALCULATE( SUM('Portfolio Reporting'[Value]),'Portfolio Reporting'[Versions] IN { "Current Fcst" }))
