Opening balances load approach

What is the best practice approach for loading opening balances to a new FCCS application. I am planning to load local subsidiary currency balances to "Opening Balance Adjustment" member. Retained earning will be loaded "Retained Earnings Prior" member with Consolidated Currency values being loaded using Historical Amount override data form. I will also be populating prior period rates for translation to work. Is there anything that i should consider with this approach or is there any other approach?
