Total Cumulative - Date Hierarchy

Hi,

Try this approach

1. Create a Calendar Table with calculated column formulas for Year, Month name and Month number.  Sort the Month name column by the Month number
2. Create a relationship (Many to One and Single) from the Date column of the Fact Table to the Date column of the calendar Table
3. To your visual, drag Date from the Calendar Table
4. Write this measure

Measure = calculate([#total amount],datesbetween(calendar[date],minx(all(calendar),calendar[date]),max(calendar[date])))

Hope this helps.
