If you have a date table and week slicer coming from that you can have 7 days behind measure to give you last week

 

last week Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-7,Day)))

 

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s.

Isnt that formula just gonna give him - 7 days so it can be between weeks depending on what day it is today?

I mean week 52 is 52 not half 51 & half 52

    Try like

    This WEEK
var _max_week = maxx(date,date[Fiscal Week])
return
calculate(sum(x),all(date[Fiscal Week]), Date[Fiscal Week] =_max_week)

last week
var _last_week = calculate(Max(Fiscal Week),datediff(date[date],-7,day))//

return
calculate(sum(x),all(date[Fiscal Week]), Date[Fiscal Week] =_last_week)
