Financial model advice

I'm shortly to be undertaking a project to produce a set of consolidated statutory accounts in BPC.

Being more experienced in using TM1, I would generally start by setting up three cubes/models for P&L, Balance Sheet and Cash flow due to the different dimension requirements of each. However, our mgmt. accounts model has all these elements in one cube which makes me question the best way to do this in BPC.

Any recommendations as to the most appropriate way to do this in BPC? Appreciate that there might not be a right answer but would like to understand the pros and cons of each method.
