It seems like you are trying to make a payment to someone, but you have given no information about the receiver’s bank information.
The receiver’s bank account can be either a BBAN or IBAN account, where BBAN is the old local Bank account type and IBAN is the new international type.
BBAN normally comes together with a clearing code, which is put in front of the BBAN number. F.ex. if the clearing code is 4310 and the bank account number is 3311987654 then the receiver’s account number sent to AMC should be 43103311987654.
IBAN always comes with a SWIFT code, so if the receiver’s IBAN number is filled, the SWIFT number must also be filled.
