DISTINCT COUNT and GROUP BY

[UsePowerBI]

Hello

I have the data:

A	1	01/01/2020
B	2	02/01/2020
C	3	03/02/2020
E	4	04/02/2020
D	5	05/03/2020
D	6	06/03/2020

How can I calculate the distinct number of Col1, where Col2 is >2 and group the results by month?

So the result should be:

Jan=0

Feb=2

Mar=1

Thanks!

Hi  @UsePowerBI ,

Here are the steps you can follow：

1. Create calculated column.

Month = MONTH('Table'[Date])

Month_mmm = FORMAT([Date],"mmm")

2. Create measure.

Measure =
var _2=CALCULATE(DISTINCTCOUNT('Table'[Column1]),FILTER('Table','Table'[Column2]>2&&'Table'[Month]=MAX('Table'[Month])))
return IF(_2=BLANK(),0,_2)

3. Result.

You can downloaded PBIX file from here.

@UsePowerBI 

you can create a column

month = FORMAT('Table'[Column3],"mmm")

then create a measure

Measure = CALCULATE(DISTINCTCOUNT('Table'[Column1]),FILTER('Table','Table'[Column2]>2))+0

@UsePowerBI , Create a measure like this

calculate(distinctcount(Table[col1]), filter(Table, Table[col2] >2))+0
