What is your objective? The subcube in HFM is a concept which applies to the application tier - not so much to the database tier. The size of the subcube is the unique number of data strips (data values for January - December inclusive, for example) for the given entity, currency triplet or Parent.Child node. You have to account for parent accounts and customs which don't exist in the database but are generated in RAM in the application tier.
So, if your objective is to find the largest subcubes, you could do this by querying the database and counting the number of records per entity/value (DCE tables) or parent.child entity combination (DCN tables). I'm not versed in SQL, but I think the script below would just tell you the schema size and not the subcube sizes.
Check out Accelatis.com for a third party software product that can do this for you. The feature is called the Subcube Analyzer and was written by the same team that wrote HFM, so they ought to know how this works :-)
