Distinct count for two columns

[naseem_1973]

Hi All,

I am a new user of Power BI. I have a table in which one primary column has a duplicate value. 

I have counted this column's distinct values. But how do I count other column values according to this column's unique values?

I have used below measuer but its not working.

CountOtherColumnByPrimary =

SUMX(

    VALUES(Demographic[MRN]),

    CALCULATE(

        COUNTROWS(Demographic),

        ALLEXCEPT(Demographic, Demographic[MRN])

MRN is primiray column.

Hi,

Drag Gender to the Table visual and write this measure

Measure = distinctcount(Demographic[MRN])

Hope this helps.

Hi  @naseem_1973 ,

Do you mean counting by [MRN] and [Gender] grouping or do you mean counting the same number in the whole [Gender] based on the [Gender] of each [MRN].

The former:

Create measure.

Measure1 =
COUNTX(
  FILTER(ALL(Demographic),'Demographic'[MRN]=MAX('Demographic'[MRN])&&'Demographic'[Gender]=MAX('Demographic'[Gender])),[Gender])

Result：

The latter：

Create measure.

Measure2 =
var _select=SELECTCOLUMNS(FILTER(ALL(Demographic),'Demographic'[MRN]=MAX('Demographic'[MRN])),"column",[Gender])
return
COUNTX(
    FILTER(ALL(Demographic),
    'Demographic'[Gender] in _select&&'Demographic'[Gender]=MAX('Demographic'[Gender])),[Gender])

Result：

If that result does not meet your expectations, you can express the expected result in the form of a picture and we can help you better.

Sir, 

I think you are not understand my query.

Mrn  Gender

123- Male

123  Male

211- Female

211-Femal

Keep in mind this scenario, I want to count 1 male and 1 female because both registrations same.
