What do %LY and %LLY represent on the data sheet?

View previous years' data on the data sheet

If you have multiple years worth of data loaded into any of your scenarios, the data sheet will automatically display how the year you are focused on compares to the 2 previous years (Last Year - LY and the year before that - LLY). You will see the previous years data below your current year totals, and the variance below that in percentage terms in the rows labeled %LY and %LLY.
