Error Creating Alternate Period Hierarchies for ASO

Hi,

I am attempting to create an alternate structure in the period dimension, which will be subscribed only to an ASO Plan Type, to replicate the functionality of dynamic time series. I typically do this through a View dimension, but I am accepting of a challenge to do it without.

I created a nested, stored hierarchy of stored/shared members, respecting all of the published ASO guidelines, which looks like this:

• YTDAlternate
  • DecYTD
    • Dec (shared)
    • NovYTD
      • Nov (shared)
      • OctYTD
        • …

However, when I go to refresh the application, I receive the below error(s):

"This date-type dimension requires all prototypes to have their shared members in same order. Member [Feb] shared members follows a different order than its previous sibling."
