We started working with Oracle Financials in Release 9.4 (you may remember the "green screen" version) and have seen the offerings increase to include:
Sub Ledger Accounting
Financial Accounting Hub
Global Consolidation Hub
Application Desktop Integration
We have implemented and upgraded the Oracle Financials Suite of Applications currently through Release 12.2.3. Our upgrade experience includes situations where the source release has been highly customized, requiring code modifications for the target release or eliminating the need for an extension altogether.
