    Rolling 3 Month Sum

    Ron Schultz

      Hi,

      I have a question for how you get the first two months of the displayed data to calculate the 3 month rolling sum.  In the attached file I have data back to January 2015, but I am displaying May 2015 to May 2016.  The first 2 months displayed only show one and two month rolling totals.  Can this be managed correctly in the Tableau report or do I need to create the summarized 3 month rolling data in the database?
