    You need  to group the categories to applied the aggregation.

     

    One way is this:

     

     

    Top2RL =
CALCULATE (
    SUM ( Table3[Value] ),
    TOPN (
        3,
        GROUPBY ( Table3, Table3[Category] ),
        CALCULATE ( SUM ( Table3[Value] ) )
    )
)

Anonymous  It works but the thing I want is, the TOPN sum to be grouped by Column1. How can I do that? This does not group by Column1 it only returns the sum of the first 10 rows.

Are you saying you want to see the top n rows with a sum for each row? If that's all, the latest desktop release makes it super easy; you just need a regular sum formula, then put a top n filter on the visual.

    Anonymous no, I want the SUM of the TOP N rows as a measure.

    For example if I have this table and I want the sum od TOP 3:

     

    A 15     

    B 20

    C 30

    D 10  ====> A 35

    A 20                B 30
    B 10                C 55
    C 25                D 10

     

    I would get 35+30+55=120

     

     

    Do you know how can I do that?

        Look

        The SumTOPNa expression is: 

        SumTOPNa = CALCULATE(sum(Table1[Column2]), TOPN (3, PieChart, SUM(Table1[Column2]), DESC))
