Hi mavn23061997 ,

 

I assume the years table is separated from the other table, create the following measure:

Values per Month = 
VAR temptable =
    ADDCOLUMNS (
        FILTER (
            ADDCOLUMNS (
                CROSSJOIN (
                    'Years_Table',
                    ADDCOLUMNS (
                        'DataValues',
                        "StartYear", YEAR ( 'DataValues'[Date ini] ),
                        "EndYear", YEAR ( 'DataValues'[End date] )
                    )
                ),
                "Flag",
                    IF ( [StartYear] <= [Years] && [EndYear] >= [Years], 1, 0 )
            ),
            [Flag] = 1
        ),
        "TotalMonths",
            SWITCH (
                TRUE (),
                [StartYear] = [Years],
                    DATEDIFF (
                        'DataValues'[Date ini],
                        MIN ( DATE ( [years], 12, 31 ), 'DataValues'[End date] ),
                        MONTH
                    ) + 1,
                [StartYear] > [Years], DATEDIFF ( DATE ( YEAR ( [StartYear] ), 12, 31 ) + 1, 'DataValues'[Date ini], MONTH ),
                [StartYear] < [Years]
                    && [EndYear] > [Years], DATEDIFF ( DATE ( [Years], 1, 1 ), DATE ( [Years], 12, 31 ), MONTH ) + 1,
                [EndYear] = [Years], DATEDIFF ( DATE ( [years], 1, 1 ), 'DataValues'[End date], MONTH ) + 1
            )
    )
RETURN
    SUMX ( tempTable, [TotalMonths] * 'DataValues'[Monthly Value] )

Now just use this measure with the years column:

I just tried it and it works, just out of curiosity if in case I had a calendar table related to start date and end date, how could the same result be achieved

    This depends on how they are related.

     

    What is the active relationship?

        Try the following formula:

        Values per Month = 
VAR temptable =
    ADDCOLUMNS (
        FILTER (
            ADDCOLUMNS (
                CROSSJOIN (
                    DISTINCT('Calendar'[Year]),
                    ADDCOLUMNS (
                        'DataValues',
                        "StartYear", YEAR ( 'DataValues'[Date ini] ),
                        "EndYear", YEAR ( 'DataValues'[End date] )
                    )
                ),
                "Flag",
                    IF ( [StartYear] <= [Year] && [EndYear] >= [Year], 1, 0 )
            ),
            [Flag] = 1
        ),
        "TotalMonths",
            SWITCH (
                TRUE (),
                [StartYear] = [Year],
                    DATEDIFF (
                        'DataValues'[Date ini],
                        MIN ( DATE ( [year], 12, 31 ), 'DataValues'[End date] ),
                        MONTH
                    ) + 1,
                [StartYear] > [Year], DATEDIFF ( DATE ( YEAR ( [StartYear] ), 12, 31 ) + 1, 'DataValues'[Date ini], MONTH ),
                [StartYear] < [Year]
                    && [EndYear] > [Year], DATEDIFF ( DATE ( [Year], 1, 1 ), DATE ( [Year], 12, 31 ), MONTH ) + 1,
                [EndYear] = [Year], DATEDIFF ( DATE ( [year], 1, 1 ), 'DataValues'[End date], MONTH ) + 1
            )
    )
RETURN
    SUMX ( tempTable, [TotalMonths] * 'DataValues'[Monthly Value] )
