Set Analysis -less than or equal to

[zagzebski]

I have the following in my set analysis expression and it works fine. However I am struggling with the syntax of this part of the expression when I want to change it to MonthYear being less than or equal to the right side of the equation. I don't know where to put the <= 

MonthYear={$(=max(MonthYear))}

Hi Zagzebski

Try like these

MonthYear= {"<=$(=Max(MonthYear))"}

Hope you get the solution

make your dimension as Date(MonthYear)

and use Date ={"<=$(=Max(Date))"} in these format
