Record to Report Process in Oracle

 Gurus,I am looking for some information on R2R. I know it is Record to report but don’t know much! Is there anyone who has done some work and who has the material and can share his/her knowledge.

The understanding is that it should cover the following processes:

RTR 01 : Journal Entry process
RTR 02 : Bank Reconciliation
RTR 03 : Intercompany transactions (Non Projects)
RTR 04 : Sub Ledger Period Close
RTR 05 : GL Period Close
RTR 06 : Consololidation
RTR 07 : Planning and Budgeting
RTR 08 : Treasury
RTR 09 : Bank Account transfaers

But the problem statement here is that apart from the above listing do we need to cover the process in which ACCRUALS, PROVISIONS, etc. is being calculated. Also let me know if the TAX calculation & reporting required to be done as part of P2P & O2C be covered in this track?
