Equity Pick Up for Alternate Entity Hierarchy

My organization is attempting to add an alternate hierarchy for management reporting and we have struggled to achieve an accurate representation of Equity Pick-up. Equity from base level entities is flowing appropriately, but anything from consol node ICPs any level down the hierarchy are not picking up anything. We've setup shared members where appropriate, new consol nodes and new holding companies (with ICP flag set to 'Yes' for each), and a Data Copy rule to bring data from the GAAP hierarchy to the Management hierarchy with mapping from the GAAP holding companies to the management holding companies.
