Create a calculated column based on another value in the same table

Hello.

 

I have a table with 3 columns (SessionID, UserID, UsedFeature) and I want to create a calculated column with a flag that is 0 if a user has never used the feature in all of his sessions, 1 if he has only sessions that used the feature and 2 if he has sessions that used the feature and sesssions that did not.

 

I attach a table to see what I mean. The column in the blue circle is the one I want to create.

 

Thanks.

    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 )

    Anonymous - You could do something like this:

    Flag = 
VAR a =  
    CALCULATETABLE(
        'Session',
        FILTER ( ALL ( 'Session' ), 'Session'[UserID] = EARLIER ( 'Session'[UserID] ) )
    )
VAR b = MAXX(a,[UsedFeature])
VAR c = MINX(a,[UsedFeature])
RETURN
    SWITCH ( 
        b & c, 
        "NoNo", 0, 
        "YesYes", 1, 
        2 
    )

    or this:

    Flag = 
VAR a =
    CALCULATE (
        MIN ( 'Session'[UsedFeature] ),
        FILTER ( ALL ( 'Session' ), 'Session'[UserID] = EARLIER ( 'Session'[UserID] ) )
    )
VAR b =
    CALCULATE (
        MAX ( 'Session'[UsedFeature] ),
        FILTER ( ALL ( 'Session' ), 'Session'[UserID] = EARLIER ( 'Session'[UserID] ) )
    )
RETURN
    SWITCH ( 
        a & b, 
        "NoNo", 0, 
        "YesYes", 1, 
        2 
    )

    Cheers!

    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] ) )

        AlB - You're absolutely correct - thank you for catching that!
