    In the Allexcepted put the column date that your are using in the charte.

    Allexcepted will remove all filter on that table except on the column you mention, so I think it Could solve your problem.

    Try...

Please take a look it this is what you're looking for:


My AverageCourse measure it this:

AverageCourse = 
IF(
    NOT(ISBLANK([Count of Logins])),
    CALCULATE(
        [SimpleAvg],
        FILTER(
            ALL(T_Logins),
            T_Logins[Event_Type]="Login" && T_Logins[Student_Course_Name] IN VALUES(T_Logins[Student_Course_Name])
        )

    )
)

What is 

[SimpleAvg]

?

 

Also, that doesn't look right because the average value doesn't change each day. I need average value for the course on each day, so it will change every day.

    cw900,

    See if this solve your problem:


    Measures:

    SimpleAvg = 
AVERAGE (T_Logins[Total])

New Avg = 
IF(
    NOT(ISBLANK([Count of Logins])),
    CALCULATE(
            [SimpleAvg],
            REMOVEFILTERS(T_Logins[Student]),
            T_Logins[Event_Type]="Login"
    )
)

      Ok that is much closer. I changed the measure to this:

      New Avg v2 =
          CALCULATE(
                  AVERAGE (CourseData[Total]),
                  CourseData[Event_Type]="Login",
                  REMOVEFILTERS(CourseData[Student])
          )
       
      This works in the example here but when I apply this to my real data it doesn't work. I think because my real table contains many other fields other than Student_Course_Name.
       
      Is there any way in that measure to say only calculate the average based on Student_Course_Name?

        Try something using Allexcepted.

        DAX is all about context and for that reason is important to have the right example.

        In my example is working fine on my side...
