@amitchandak ,

Thanks for sharing the gem of a document. i guess LastYear Week is missing. suppose if my filter is send on week 3. it should give me sales for ly week and this year week.

@Anonymous , Try like

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