I am trying to calculate a 6 month rolling sum of the 'Booked' column pictured below. I am still learning Power BI and can't seem to figure out a way to do this. Basically, the perfect solution would create another column where each month had a total for the previous 6 months of booked dollars. So for example, 2017-06 would be (1,091,031 + 1,108,326 + 135,000 + 125,327 + 236,515 + 101,296) = 2,797,495
Thank you!!!!
