Oracle's recommended approach to performing consolidations when all of your subsidiaries can share the same ledger with their parent company and all reside on the same application instance is to use General Ledger's Financial Reporting functionality to produce consolidated reports by balancing segment where each report represents a different subsidiary. Any eliminating entries can be entered in yet another separate balancing segment. Therefore, option A is correct. Option B is incorrect because you don't need to use Oracle Hyperion Financial Management for this type of consolidation. Option C is incorrect because you don't need to use General Ledger's Balance Transfer programs to transfer subsidiary ledger balances to the parent ledger, and then enter eliminating entries as a separate balancing segment in the parent ledger. Option D is incorrect because you don't need to define multiple ledgers for consolidation and report on ledger set.
