Anonymous , In your date table you need to have columns like these. Important is Week Rank. That can be done on Year week in week table. But Date/Week should be separate table

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Number = WEEKNUM([Date],2)
Week = if('Date'[Week Number]<10,'Date'[Year]*10 & 'Date'[Week Number],'Date'[Year]&'Date'[Week Number])
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)

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

You can have measure like

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