Hi, I want to view past sales data in the same view when I'm looking at the current year sales..
Right now, I use (Week-100) to look one year back. I cannot use both (week-100) and (week-200) because it gives me the same number... So Is there some kind of set analysis that I could use to say "Show me the Sales when it is (week-200) or 100 less than (week-100)
