    Hi  Anonymous ,

    Try this:

     

    NewColumn =
VAR Num_Yes_ =
    CALCULATE (
        COUNT ( Table1[UsedFeature] ),
        ALLEXCEPT ( Table1, Table1[UserID] ),
        Table1[UsedFeature] = "Yes"
    )
VAR Num_No_ =
    CALCULATE (
        COUNT ( Table1[UsedFeature] ),
        ALLEXCEPT ( Table1, Table1[UserID] ),
        Table1[UsedFeature] = "No"
    )
VAR Num_Total_ = Num_Yes_ + Num_No_
RETURN
    SWITCH ( Num_Total_, Num_No_, 0, Num_Yes_, 1, 2 )

AlB  Thank you it works perfectly. I should really start looking into using variables. They are very useful.

 

Anonymous  Thanks for your answer. I didn't try your solytion as AIB's answer worked for me, but it looks like it will work as well.

    Hi Anonymous

    Interesting solution. I'm curious, why do you need the CALCULATETABLE  in VAR a? Wouldn't you get exactly the same table  without it? i.e.: 

     VAR a =  
     FILTER ( ALL ( 'Session' ), 'Session'[UserID] = EARLIER ( 'Session'[UserID] ) )

     in fact, the ALL() is superfluous since no filter context is present: 

     VAR a =  
     FILTER ( 'Session', 'Session'[UserID] = EARLIER ( 'Session'[UserID] ) )
