Constant Average

Hi sagadgreat ,

My sample data is this.

1.Create a measure to get the 3 month average.

3 mo ave = 
DIVIDE (
    CALCULATE (
        SUM ( 'Table'[Net Sales] ),
        FILTER (
            ALLEXCEPT ( 'Table', 'Table'[Customer], 'Table'[Year] ),
            [Month] IN { "Jan", "Feb", "Mar" }
        )
    ),
    3
)

2.Create a measure to get the difference between net sales and the 3 month average.

difference = [3 mo ave]-MAX('Table'[Net Sales])

3.The result is as follows. Let the filter select a single select.

You can check more details from here.
