The ledger is a basic concept in Release 12. The ledger replaces the 11i concept of a set of books. It represents an accounting representation for one or more legal entities or for a business need such as consolidation or management reporting. Companies can now clearly and efficiently model its legal entities and their accounting representations in Release 12. This seems to be a major area in getting success of the shared service center and single instance initiatives where many or all legal entities of an enterprise are accounted for in a single instance, and data, setup, and processing must be effectively secured but also possibly shared.

Now, legal Entities can be mapped to entire Ledgers or if you account for more than one legal entity within a ledger, you can map a legal entity to balancing segments within a ledger.
While a set of books is defined by 3Cs

  1. chart of accounts
  2. functional currency
  3. accounting calendar,

The addition in this list the ledger is defined by a 4th C: the accounting method.

This 4th C allows you to assign and manage a specific accounting method for each ledger. Therefore, when a legal entity is subject to multiple reporting requirements, separate ledgers can be used to record the accounting information.
Accounting Setup Manager is a new feature that allows you to set up your common financial setup components from a central location.
