Hi @sraj,

Is your issue solved? If the issue has been solved, please adopt the solution to help others.

You need a weeknum column to define the same period last year.

Just like:

Weeknum = 
CONCATENATE(YEAR('Table'[Date]),WEEKNUM('Table'[Date]))

Create measure as:

Measure = 
var _weeknum=CONCATENATE(YEAR(MAX('Table'[Date]))-1,MAX('Table'[Weeknum]))
return
CALCULATE(
    MAX('Table'[Value]),
    FILTER(
        'Table',
        'Table'[Weeknum]=_weeknum
    )
)

If you still have some question, please don't hesitate to let me known.‌‌

Best Regards,

@sraj , same week day is 364 days behind

example, with help from date table

Week Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-364,Day))

how to deal with week vs week refer to my blog

It need a new column for week rank in date Table

Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

measures examples
This Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
Last year Week= CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))
