new formula to return the number of children for the selected member.
Useful when you you cget and want to find cross data point that doesn't exist.
This is quite an esoteric requirement, and can be achieved using a CGETMDX function with a query like:
with member measures.childCount as
[Date].[Fiscal Periods].[Fiscal Year].&2014 on 0,
measures.childCount on 1
