How to use 2 Dropdown box in webapplication for date range selection

Dear all,

I am working on a report that will show 2 drop down boxes. These should be used as a date range.

This works fine if I use 2 variables as a date range on 0CALYEAR. However I dont want the user to fill in the dates but selecting the dates with 2 drop down boxes.

I cannot manage to get this to work. I saw some comments about user exits in the forum but I cannot figure it out if there is an easier way.

Could you give me an idea of what to do?

Thanks a lot,

Andreas
