Calculate Measure Count

[Anonymous]

I have a table with such columns:

Clients	Point	Date
Client 1	P1	01.01.2019
Client 1	P1	01.01.2019
Client 1	P2	01.01.2019
Client 2	P1	01.01.2019
Client 2	P1	01.01.2019
Client 3	P3	01.01.2019
Client 4	P1	01.01.2019

I need to count clients, who visited points P1 && P2, I tried different ways, but nothing.

@Anonymous Hope you are looking for something like this...

Test142 = 
VAR _P1 = SELECTCOLUMNS(FILTER(Test142Measure,Test142Measure[Point]="P1"),"Client",[Clients])
VAR _P2 = SELECTCOLUMNS(FILTER(Test142Measure,Test142Measure[Point]="P2"),"Client",[Clients])
VAR _Both = CALCULATE(DISTINCTCOUNT(Test142Measure[Clients]),INTERSECT(_P1,_P2))
RETURN _Both
