Budget Transactions - Original Estimate / Revised Estimate - where are the tables??

Summary:

I am looking for the Oracle transactional tables that are posted to when creating budgets (not control budgets but 'reporting' budgets and not balances but transactions).

I am looking for the Fusion Financials database tables that hold the post interfaced data for budget creation, which is to say transactional level data - not balances and reporting budgets (Original Estimate, Revised Estimate) not the XCC_ control budgets.

Back in the e-business days these were posted into gl_je_lines et al as actual_flag = 'B', but no more - so I am looking for the equivalent tables for Fusion.
