I have a report that has a year field that I am pulling from our system. I want to pull the current year and one year ago (17 and 16). Every year I have to go in and add the current year and get rid of of date 2 years ago. For example, at the beginning of 2017, I had to go in and remove 15 (for 2015) and add 17 (for 2017). Is there a way to just have it look at the current year and then 1 year ago so I don't have to go in and add the current year and take out the oldest year?
