    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] ) )
    )
)

TOPN doesn't guarantee any particular sort order to the results, but the results are the correct top N results. So summing them up should work fine; 1 + 2 + 3 + 4 is the same as 1 + 3 + 4 + 2. What is wrong with the results you're getting? Can you give a sample that doesn't give the correct sum?

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?

        Anonymous the formula Vvelarde gave should work for that.
