Hi Greg,

 

It did work. I will accept as solution. I also added another column and some data as below. c3 will be a column in the table visual. The second column shows all counts as before. can I have the DAX that show the distcount with filter c3 but without c2? I tried write another DAX M3 but looks like it cannot see [c3].

    Hi Greg,

     

    I found another issue. Here assume c3 is always existed in all selection of c2 with is good. But if I change the data a little bit, replaced one "c" to to "b" (hightlighted). Then when I choose the "c" in the slicer, because "c" is nolonger existed with any rows having ca, the result table doesn't have record for ca any more. Is it possible even the selection doesn't exist in that group, the total count still showing. Means in this case, for row ca, m1 will be 0 and m3 will continue show 2?
