Calculate Revenue Per Month between two dates

Thanks for your reply lbendlin 

Here is a sample of the Opportunity table

I would like to have a visual with the the Year and Month columns from my Date Table and the Monthly Revenue populated in the months where the Start and EndDates are valid, Date table has a one to many active relationship with the StartDate.

I ahve created a measure which populates the month, it's a running total, but it doesn't sum up in the visual

VAR MaxDate =
    MAX ( 'Date'[Date] )
RETURN
    CALCULATE (
        SUM(Opps[MonthlyRevenue]),
        KEEPFILTERS ( Opps[StartDate] <= MaxDate
            && Opps[EndDate] >= MaxDate
            )
            ,
        ALL ( 'Date')
)

Thanks in advance
