With the limited example and data provided, I think what you are saying is that there is a filter for the last date?

If so,

Measure Name =

Var StartDate = DATE(YEAR(TODAY()), MONTH(TODAY()),1)

Var EndDate = SELECTEDVALUE( [Assumed Date Table with a Date Field], Default Value (You can use TODAY() )

RETURN CALCULATE( SUM(of some field), FILTER(ALL(some date field),DATESBETWEEN (some date field,StartDate,EndDate

)
