    Hi Vikas_Jayara12 ,

     

    As far as I know, there isn't a DAX formula to calculate data in previous week. I suggest you to add a [Start Date] which is mentioned by the blog shared by ribisht17 to determind the week.

    DimDate Table:

    DimDate = 
VAR _BASIC = ADDCOLUMNS( CALENDARAUTO(),"Year",YEAR([Date]),"Month",MONTH([Date]),"WeekNum",WEEKNUM([Date],2))
VAR _ADD = ADDCOLUMNS(_BASIC,"Start Date",[Date] - WEEKDAY([Date],2)+1)
Return
_ADD

    Then create a measure based on DATEADD() function.

    Last Week Sales = 
CALCULATE(SUM('Table'[Sales]),DATEADD(DimDate[Date],-7,DAY))

     

    Best Regards.
