Creating Week Over Week View

[NL-Nicolas]

Hi all!

I have a new measure that I am using this code on:

Last Week Sales = CALCULATE(SUM('DayfileSummary'[NetSales]),DATESINPERIOD(DayfileSummary[DF_BusinessDay],SELECTEDVALUE(DayfileSummary[DF_BusinessDay]),-7, DAY))

Essentially what the column needs to produce is a week prior to the selected date in a slicer. I need the total so I can do a change % column but I cant seem to get the Column to show the week before it always shows same date

@NL-Nicolas , With help from a column like

Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

Create measures
This Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))

Thank you so much for the help! Of course my client has to change the issue and wants it the same week 1 year ago. But now that I have the basics of the dax and columns I have enough to play with! You rock thanks!
