IDESCENDANTS in AGG

Summary:

Content (required):

We have an aggregation as part of our calc people plan rule using just an agg function. This doesn't seem to work unless @idescendants is included after the agg. Can anyone explain why that is needed? In our financial cube an agg function works just fine. Reading about the @idescendants function itself hasn't helped clarify for me.
