Problem: How do you return the first N months of each year in the time hierarchy? It must be dynamic (no static sets, because who wants to go back every year and fix it?), and the user wants to be able to select the number of months that are displayed.

Solution:

generate
(
   [great_outdoors_company].[Years].[Years].[Year]
   , head
     (
        descendants
        (
           currentMember([great_outdoors_company].[Years].[Years])
           , [great_outdoors_company].[Years].[Years].[Month])
     , #prompt('n','integer')#
     )
)

The generate function will evaluate the head(descendants(currentMember)) expression for each member in the years level.
