All of the base currency values on the transactions in a journal must balance before the journal can be posted. This means the total of the debit base currency values must equal the total of the credit base currency values.

If these values do not balance, you can determine how this imbalance should be corrected. It can be corrected automatically by the system, or you can force the operator to balance the journal manually. If it is corrected automatically, the balancing amount is posted to a nominated account, for example a suspense or rounding difference account.

When you define a business unit, you can determine the balancing rules for the base currency. The balancing can be Automatic or Manual. If it is Automatic, you must identify the balancing accounts and you can set a limit on the balancing amount to ensure very large adjustments are not made automatically.

In a multi-currency environment you can also determine whether or not the transaction currency, second base/reporting currency, and fourth currency values must also balance on a journal, and if so, identify the balancing accounts for each.

When you set up a business unit using Business Unit Setup (BUS) you must define a posting rule for each currency value. This determines whether or not the currency value is required on each ledger posting transaction, whether it must be entered manually or can be calculated.

There are several options available, only some of which are available for each type of currency value and depending on which currency is the pivot:

Undefined (or blank) - this option prevents a currency value being entered.

Only present if entered - this option allows a currency value to be entered manually on a transaction. However, the value is not mandatory, so if it is not entered the value is not calculated.

Must be entered - this option can be used to force a currency value to be entered manually on every journal transaction.

Calculated if not entered - this option means the currency value can be entered, or if it is not entered, it will be calculated automatically from another value entered (depending on the pivot currency).

Always calculated - this option means the currency value is always present on every transaction and is always calculated by the system.

Rate Only - this option means that the currency rate can be entered but not the currency amount. This option is only available for the fifth currency and all amounts for this currency are calculated when required.
