Countax Example

Hi Heinrich ,

Thanks for the reply Greg_Deckler , it is an important step forward in resolving the issue.

I used the example data you provided and selected Create a measure in the Data view.

Please try:

count = 
CALCULATE(
    COUNTAX('Export_User_Global', 'Export_User_Global'[Application]),
    FILTER(
        'Export_User_Global',
        'Export_User_Global'[Application] = "Teams Classic" || 'Export_User_Global'[Application] = "New Teams Client"
    )
)

The page effect is shown below:

If you have any other questions please feel free to contact me.

The pbix file is attached.

Best Regards,
