I want to use the Multi-GAAP Dimension in order to report GAAP and Non-GAAP. I was thinking about utilizing FCCS_Local GAAP as my load point, then creating a new member called "Non-GAAP adjustments". Then using the Multi-GAAP Parent member to view the Non-GAAP numbers(Sum of Local GAAP and Non-GAAP Adjustments). However it seems as though Multi-GAAP does not consolidate its children. What would be the best approach for this?
