Parallel Currencies in General Ledger Accounting 
You can use the General Ledger Accounting function described below, if you do not need valuation parameters (acquisition and production costs (APC)/depreciation terms) for group consolidation that are different from your local valuation, but only need amounts in a foreign currency.
The Financial Accounting (FI) component component enables you to manage all values of one company code, on the same accounts, in up to two additional parallel currencies. To do this, you can define two parallel currencies for each company code in Customizing for Financial Accounting.
NoteMake the following specifications for each parallel currency:
Currency type in accordance with the function of the currency (for example group currency)
Exchange rate type for the currency translation
Source currency for the currency translation
Date (for example document date) for the translation
It is also possible to update APC and depreciation values that are posted in Asset Accounting in parallel currencies. The asset values can be updated in Financial Accounting in parallel in several currencies in the same accounting document as the amount posted in local currency.
Prerequisites
To do so, you have to manage a depreciation area with the following properties for each currency:
Currency type and currency of the depreciation area are identical to those of the corresponding parallel currency in the company code in question.
The depreciation area has identical depreciation terms and identical acquisition values to the depreciation area that updates values to the G/L accounts.
The system then automatically updates the corresponding posting documents with the additional values from these depreciation areas. The values from the foreign currency depreciation areas do not have to be posted explicitly (according to their posting setting) to General Ledger Accounting.
The system can also handle parallel currencies for depreciation areas that are posted periodically to General Ledger Accounting rather than online.
Features
The system translates APC acquisitions into the parallel currency based on the exchange rate type (historical valuation). The system does not translate depreciation amounts. Instead, they are calculated in the given currency, using the depreciation terms in the depreciation area. This method guarantees that the net book value zero is reached during the defined useful life in all depreciation areas with parallel currencies. The system also does not translate APC retirements and proportional value adjustments directly. Instead, the system calculates the proportional amount of APC being retired based on the amount retired in the local currency area.
Caution
It is not possible to begin using the parallel currency functions after the company code is already live. You have to make the system settings described here before the given company code goes live.
