Query on PreviousWeek Function

Vikas_Jayara12 — Sun, 07 Aug 2022 12:51:06 GMT

Hi Team,

I have used PREVIOUSDAY, PREVIOUSMONTH, PREVIOUSQUARTER & PREVIOUSYEAR function as well. However, unable to find PREVIOUSWEEK function. Just wanted to know why we don't have Previousweek function in DAX. Any specific reason?

Regards,

Vikas Singh Jayara

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.
