@Ramachandran ,

Rolling 12 before 12 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],eomonth(MAX('Date'[Date]),-12),-12,MONTH))

Rolling 12 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-12,MONTH))

Hi, After updating the Rolling 12 before 12 month logic code, I'm getting the Rolling value for all the month but not latest 12 month alone. the result is below

But I want to show only last 12 months data alone.

anything, I have to add condition for this.
