Conversion rules for internal and external initialization

Internal initialization conversion rules

For internal currency initialization, these standard conversion rules apply:

Currency amount (amount in a specified currency)
Currency amounts can be stored in up to three home currencies. The amount is converted into each of the new home currencies. Conversion takes place for each new home currency. The currency rates are taken from the CI Rates (tccri7100m000) session.
- Single or dependent multicurrency system
  The transaction amount is converted to the reference currency. In a dependent currency system, the amount in the reference currency is then converted into the other home currencies.
- Independent multicurrency system
  The amount in the transaction currency is converted directly into each of the home currencies.
- Standard multicurrency system
  
  The amount in the transaction currency is converted directly into the local home currency. Depending on the translation method for each individual reporting home currency, either the amount in local home currency is converted into the amount in the particular home currency, or the home amount is calculated directly from the transaction amount.
  
  When Operation Management tables, Integration Transactions (tfgld482), or FAM tables in Financials are converted, reporting amounts and rates are directly translated from the transaction currency.
Rate/Rate factor
Depending on the currency system after conversion, the rates are taken from the CI Rates (tccri7100m000) session or the rates are calculated based on the converted amounts. The corresponding rate factors are changed as required.
Default currency
The default home currency for registering currency data is replaced with the new home currency.
Sole home currency amount
Use this rule in an independent currency system if the amount is not available in the transaction currency. The amount in the local home currency is converted into amounts in the new home currencies.
Sole amount
The currency of the amount in home currency is not available. To convert the amount, you must indicate whether the amount is in the reference currency or in the local home currency of the financial company.
Rate determiners
Some rate determiners cannot be used in specific currency systems. If the currency system changes and the rate determiner cannot be used in the new currency system, the rate determiner is changed to the most similar rate determiner that can be used in the new currency system. If the rate determiner can be used in the new currency system, the rate determiner is not changed.

External initialization conversion rules

For external currency initialization, these standard conversion rules apply:

Transaction-currency amount
During external conversion, amounts in transaction currencies are converted to amounts in the new transaction currency, which is euro. The currency rates are taken from the CI Rates (tccri7100m000) session.
Transaction currency
During external conversion, the transaction currencies are changed to the new transaction currency, which is euro.
Rate and rate factors (external)
The currency rate between the transaction amount in the new transaction currency (euro) and the company’s home currency or currencies is calculated.
