Issue with quick measure for running total

Try to use YTD for cumulative like

YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(('Date'[Date]),"12/31"),'Date'[Date]<=today()) //change end date of year//stop at today


YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(('Date'[Date]),"12/31")) //change end date of year
This Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD((ENDOFYEAR('Date'[Date])),"12/31")) //change end date of year

Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31")) //change end date of year
Last YTD complete Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31")) //change end date of year

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
