Exchange Rate or Foreign Exchange Processing refers to the handling of foreign exchange rates and conversions when a payment return involves a cross-border or foreign currency transaction.

• If the original transaction credit currency is different from settlement currency, then the option Re-Pickup FX Rate from the R-Transaction Preference tab is referred from the Generic Wires ISO Outbound Network Preferences (PSDOGWNP) maintenance screen for the Host code, Network code, and Transaction Type as Incoming combination.
• If the option is set as Yes, then the Internal or External exchange pick-up processing is done.
  • The external exchange rate processing is done if the External FX Applicable option is set as Yes in the Generic Wires ISO Outbound Network Preferences maintenance (PSDOGWNP) screen. The External Exchange Rate System is picked up from the External Exchange Rate mapping maintenance (PMDERMAP). An External Exchange Rate request XML is sent to the external exchange rate system and a record is logged into the Exchange Rate Queue (PQSEXEXQ) with Queue Code as External Exchange Rate Queue.
  • Internal exchange rate processing is done if the External FX Applicable option in the Generic Wires ISO Inbound Network Preferences maintenance (PSDIGWNP) is set as No. The exchange rate pick-up is done using STANDRD – MID rate.
• If the option is set as No, then:
  • The system picks the exchange rate applied on the original pacs.008/pacs.009 messages and applies the exchange rate for calculating the credit amount.
  • In case of the external exchange rate is applicable, then the value date received from the External FX system is updated as the return transaction Settlement Date. There is no change in the Activation Date.
