How to extract a subledger foreign currency invoice report to tie back and validate GL Revaluation

How to extract a subledger foreign currency invoice report to tie back and validate GL Revaluation calculations for audit purposes (EBS R12)?

For audit compliance and verification purposes, we need to provide a clear data lineage trail connecting our GL Revaluation Journals back to the individual open source transactions in our subledgers. Specifically, we want to reconcile the entered foreign currency balances being revalued in General Ledger directly against the underlying open foreign currency invoices in Payables and Receivables.
