amirabedhiafi , Refer my post on WOW, You can create Week Rank in You date table and Use that.
Last 2 weeks = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-2 && 'Date'[Week Rank]<=max('Date'[Week Rank])))

amitchandak I modified it to :
Last2weeks = CALCULATE(SUM('COVID Data'[COVID Cases]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-WeekRank[WeekRank Value] && 'Date'[Week Rank]<=max('Date'[Week Rank])))after creating the Week Rank Calculated Column in the Dimension Date.But I can't see the value :
