DAX count in date range (slicer)

Hi togheter,

I got a challange where I can need some support / hints of the community 🙂

The data source is a list where a row is generated every time a student take an exam. Looks like this:

 

On top of that data source, I need an report where I see the levels and the number of students who are in that level depending on the time slicer. If a student is in two levels, it should only take the higher level.

 

I tried the following calculation:

 
 Number of students per level = 
 CALCULATE (
      DISTINCTCOUNT ( List[STUDENT] );
      FILTER (
           'List';
           'List'[LEVEL]
                = CALCULATE (
                    MAX ( List[LEVEL] );
                    ALLEXCEPT( List; List[DATE])
                  )
      )
 )

As you can see in the second screenshot, John is counted two times.

Anyone a solution and hint?

Thanks in advance!

    Hi bobbarker ,

     

    check this out

    Number of students per level =
VAR MaxLevelPerStudent =
    SUMMARIZE (
        ALLEXCEPT ( List, List[DATE] ),
        List[STUDENT],
        "@LEVEL", MAX ( List[LEVEL] )
    )
RETURN
    COUNTROWS (
        FILTER ( MaxLevelPerStudent, [@LEVEL] = SELECTEDVALUE ( List[LEVEL] ) )
    )

    Hi bobbarker ,

    This is a cool question but please never post pictures of your data but a copy or a link to a PBIX/xlsx file so we can actually help you create the required DAX. This is potentially a complicated measure and having some testdata helps in developing it. 

     

    Is it possible to share that?
    Thanks!

     

    Kind regards
