3.3.5 Ordering Customer Population

System defaults the IBAN linked to the debit account as the Ordering Customer (Field 50) Party Identifier when the 'Debtor IBAN Required' flag’ is checked in the Source Network Preference (PMDSORNW) for Customer Transfer Type transactions.

For transactions booked due to an incoming MT101 message, the name and address details of the external customer input (STDCIFCR) are populated when the system parameter value is 'Y.'
