Earlier Function

amaniramahi 

how exactly do you filter by product? show please full wrong sentence.

in the most common case it can look like

CACLCULATE(SUM(TABLE[QTY]),
FILTER(TABLE, 
DATEADD(TABLE[DATE].[Date],1,YEAR)=EARLIER(TABLE[DATE].[Date])
&&
TABLE[Product] = EARLIER(TABLE[Product])
)
)

amaniramahi , Try a new column like

sumx(filter(Table,Table[Product] =earlier(Table[Product]) && year(Table[Date]) = year(earlier(Table[Date]))-1),TABLE[QTY])

Measure

example with date table

YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD('Date'[Date],"12/31"))
Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))

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 :
