    Hi Anonymous ,

     

    We can create a measure as below by DAX.

    Measure = 
VAR a =
    CALCULATE (
        SUM ( 'Table'[value] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Monthno] <= MAX ( 'Table'[Monthno] ) ),
        VALUES ( 'Table'[item] )
    )
VAR b =
    CALCULATE (
        COUNTROWS ( 'Table' ),
        FILTER ( ALL ( 'Table' ), 'Table'[Monthno] <= MAX ( 'Table'[Monthno] ) ),
        VALUES ( 'Table'[item] )
    )
RETURN
    DIVIDE ( a, b )
