How to count rows with additional logic (countrows/countx)

Hey,

maybe this measure provides what you are looking for.

Countrows Summarize = 
COUNTROWS(
    SUMMARIZE('Table1'
        ,Table1[Task]
        ,Table1[Config.]
    )
) 

It results to 6.

Using SUMMARIZE allows to create a table using just the columns you want.

You can also use
ADDCOLUMNS(
    SUMMARIZE(...)

    ,"NewColumnName 1", Expression

    ,...
)

For more examples using SUMMARIZE and ADDCOLUMNS please have a look here:

Hopefully this is what you are looking for

Tom
