For a cross currency payment transaction where debit currency and transfer currency are different, exchange rate maintained for the transaction branch in the core system is considered.

If small FX limit is defined in Network Currency Preferences, then the auto rate pick up happens only if the transfer amount is within the small FX limit. If Small FX limit is not maintained auto rate pick up is done for all cross currency payment transactions without any limit check.

For an Outbound transaction limit check is based on the small FX limit specified in Network Preferences for transaction type 'Outbound’.

Exchange Rate Type is based on Network preferences maintained. Buy/Sell indicator is derived by the system based on the currency pair maintenance available.

If the transfer amount is above the small FX limit specified, system checks whether External Exchange Rate is applicable in Network Preferences.

If external system is available then system interfaces with external system for receiving the exchange rate.

Response from External Exchange Rate system is failure or timed out
