Chart of Accounts:
Chart of Accounts (COA) determines how your accounting information is collected, categorized, and stored for reporting purposes. In Oracle Financials, all accounts are identified by a unique Accounting key Flexfield combination, which is your COA structure. The Accounting Flexfield (AFF) consists of multiple segments, such as those for company, cost center, and account. One full AFF is called a combination.You assign each account the qualifier of asset, liability, owner's equity, revenue, or expense.

Subledger Accounting:
Sub Ledger Accounting (SLA) introduced in Release 12, provides a common repository of all your accounting information.

Just as Oracle General Ledger stores balances and journals, Subledger Accounting stores subledger balances and subledger journals for all of your subledgers that require accounting.

In Release 11i the transactions and distributions represented the accounting. In Release 12 however, distributions on transactions in subledgers are considered to be the default accounting and should therefore not be used for reconciliation purposes. The reason is that subledger accounting enables you to change the accounting for transactions so it is different from the default accounting. Therefore, the subledger accounting becomes the single source of truth for accounting reconciliations.

Things to Ponder:

1. Using more GL account KFF Segments doesn't affect the performance as the application uses the CCID (Code Combination ID) and not run the processes via the concatenated segments. However more the segments the more GL manual entries.
