4 weeks average based on weekrank

Hi Anonymous 

I build two table to have a test.

Date Table:

Weeknom and Rank columns are calculated columns.

Weeknom = WEEKNUM('Date'[Date],2)

Rank = RANKX('Date','Date'[Date],,DESC,Dense)

Result:

Value Table:

Build Value measure in Date table:

Value = CALCULATE(SUM('Value'[Value]),FILTER('Value','Value'[Date]=MAX('Date'[Date])))

Then I build a measure to achieve your goal.

4 weeks average =

VAR _Totalvalue= SUMX (

        FILTER (

            ALL ( 'Date' ),

            'Date'[Rank]

                <= MAX ( 'Date'[Rank] ) + 3

                && 'Date'[Rank] >= MAX ( 'Date'[Rank] )

        ),

        [Value]

    )

return

IF (

    MAXX ( ALL ( 'Date' ), 'Date'[Rank] ) - SUM ( 'Date'[Rank] ) >= 3,

    DIVIDE(_Totalvalue,4),

   BLANK()

)

Result:
