Rank based on latest date

[daniellerp]

Hello, 

I have a data set with 3 weeks of sales data for products. I need to rank the products by the latest week's sales only and I still need to be able to display the sales totals for the other weeks as well. 

Below is a simplified version of the data set. I want to rank the products based on the highlighted info. 

Here's the output I'm trying to get to: 

Any suggestions would be greatly appreciated!

@daniellerp , Create a measure like this and create Rank on that. Better to separate date table

Last Week =
var _max = maxX(allselcted('Date'), 'Date'[Week Rank])
return
CALCULATE(sum('order'[Qty]), FILTER(('Date'),'Date'[Week Rank]=_max))

or

Last Week =
var _max = maxX(allselcted('Date'), 'Date'[Week Rank])
return
CALCULATE(sum('order'[Qty]), FILTER(ALLselected('Date'),'Date'[Week Rank]=_max))

or

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