Issues with filtering when a specific measure is applied

Hi Anonymous ,

As you correctly point out, this issue is related to the filter context. When filters are applied, they change the context in which the metric is calculated.

Please try:

MonthVSAverage = 
VAR SelectedDepartment = SELECTEDVALUE('Department'[DepartmentName])
RETURN
IF(
    SelectedDepartment = "A",
    CALCULATE(
        IF(
            ISBLANK(MAX('Table'[Average Rating Past Month])), 
            "No reviews past month",
            MAX('Table'[Average Rating Past Month]) - MAX('Table'[Overall Average Rating])
        ),
        'Department'[DepartmentName] = SelectedDepartment
    )
)

You can change 'SelectedDepartment' to whatever data you have in the Filter, in this case 'A' 'B' 'C'.

I know it is a bit of a pain in the ass but it is an alternative.

The result is ideal.

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