Rollup

Hi Anonymous 

Does your "Roll UP" mean that you want to get cumulative sum result by month?

You can try my way. Firstly build a date table by dax code.

Date = ADDCOLUMNS(CALENDARAUTO(),"Year",YEAR([Date]),"Month",MONTH([Date]),"YearMonth",YEAR([Date])*100+MONTH([Date]))

Build a relationshio between date table and your fact table by date column.

Then build a measure.

Roll UP = CALCULATE(SUM('Table'[Value]),FILTER(ALL('Date'),'Date'[YearMonth]<=MAX('Date'[YearMonth]))) 

Result is as below.
