Valuing Foreign Currency Loans

Procedure
Valuation
Special items for gains and losses resulting from fixed euro rates
The system posts gains and losses resulting from the changeover to the euro to the accounts for realized gains and losses.
If you opt to create special items for these gains and losses, you need to do this manually in FI.
You also need to write back the special items manually.
