In Oracle Fusion General Ledger, statistical balances (e.g., number of employees, floor space) are recorded using a special currency code, conventionally 'STAT'. For the system to process these non-monetary amounts correctly, the currency must be explicitly defined as statistical. This is achieved by enabling the "Statistical Unit" option in the currency's configuration. If this option is not enabled, the system cannot record statistical amounts in journals, as it treats 'STAT' like any other monetary currency.

B. The derivation flag is used for reporting currency ledgers to define how conversion rates are derived; it is unrelated to statistical balances.

C. The STAT currency is not an official ISO 4217 currency, so the ISO currency flag should be disabled. Enabling it would be incorrect.
