Hi ApurvaKhatri

 

The trick is get an index calculated column to sort Weeks. (You can use power query)

 

This is the result

 

 

 

And the measures in my case are...

 

Total Sales = SUM(Sales[Sales]) 
Total Sales PW = 
var thisweek = FIRSTNONBLANK(Sales[Index];1)
var prevweek = LOOKUPVALUE(Sales[Index];Sales[Index];thisweek-1)
return
CALCULATE([Total Sales];ALL(Sales[Date]);Sales[Index] = prevweek) 
Variance = [Total Sales] - [Total Sales PW]

I hope this helps

 

Regards

Thanks for the solution. But in my case, sales is a measure so its not working
