count with parameter

Hi  Vitor_sp_bo ,

Do you mean using the parameters in Power bi desktop to count, I have an example here

I created some data:

Custom rules:

Use parameters to display the top N names, and calculate how many IDs the top N names in each group have.

Here are the steps you can follow：

1. Modeling – New parameter.

 

2. Create measure.

rank = RANKX(ALL('CountTable'),CALCULATE(SUM('CountTable'[Amount])),,ASC)

count=
COUNTX(FILTER(ALL(CountTable),'CountTable'[group]=MAX('CountTable'[group])&&[rank]<=[Parameter Value]),[group])

3. Result:
