    Hi,

     

    you can add a custom Column in powerquery to your calendar:

    for example for previous week.

    = Table.AddColumn(#"YourPreviousStep", "LastWeek", each if Date.IsInPreviousWeek([Date]) then "Yes" else "No")

     

    and then you can you can build your measure with filter on those columns

    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)

         

        I

        Check if this can help

        This week sales = 
var _date = date(year(today()),month(today()),day(today()))
var _Week_ED = _date + (-1*WEEKDAY(_date)+1)
var _Week_SD= _date +(7-1*WEEKDAY(_date))

Return 
CALCULATE(sum(Sales[Sales Amount]),all('Date'),Sales[Sales Date]>=_Week_SD && Sales[Sales Date]<=_Week_ED)


Last week sales = 
var _date = date(year(today()),month(today()),day(today()))
var _Week_ED = _date +( (-1*WEEKDAY(_date)+1)-7)
var _Week_SD= _date +((7-1*WEEKDAY(_date))-7)

Return 
CALCULATE(sum(Sales[Sales Amount]),all('Date'),Sales[Sales Date]>=_Week_SD && Sales[Sales Date]<=_Week_ED)
