Hi, @AOD 

It is solved by calculation column. First calculate the year of the previous year, and then output the total amount of the previous year.

Previous year = 
DATEADD ( 'Table'[Year], -1, YEAR )

Previous year Amount =
CALCULATE (
    MAX ( 'Table'[Current year Amount] ),
    FILTER ( 'Table', 'Table'[Year] = EARLIER ( 'Table'[Previous year] ) )
)

@AOD , If you need this as a new column

last year = sumx(filter(Table, [Year] = earlier([Year]) -1) , [Current year] )

for measure prefer to have separate year table(say Date) joined to this table 

Curr Year = CALCULATE(sum('Table'[THis year]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])))
Last Year = CALCULATE(sum('Table'[THis year]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])-1))
