The MT103 is a SWIFT message format used for making payments. MT103 SWIFT payments are known as international wire transfers, telegraphic transfers, standard EU payments (SEPA payments), LVTS in Canada, etc. A swift MT103 is a message to a customer showing the credit transfer for a single payment. It is an advanced version of the original MT100 message which had a wide range of options to describe exactly how the payment should be made. But the MT 103 is so flexible, thus it does not promote Straight through Processing and has been replaced by the MT103+ message.
