Prior year Matrix column

Not clear,

In case you have a date table and need YTD or prior YTD, you can use datesytd and totalytd . In both these, you can give year end date

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

Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))
Last YTD complete Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"))
Last to last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-2,Year),"12/31"))
Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))
Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd(dateadd('Date'[Date],-1,Year),-21,Day))

"12/31" is year-end date, you can change it say "3/31", year end in march

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 :
