How to generate MT103 in XML2 with LAU

Hi Gurus,

We are on ECC6.0 and now looking at architecture of transmitting MT message to SWIFT Aliance gateway for outgoing payment, but the requirement is to place encryption on the payment message until it gets dispatched to SWIFT Aliance.

Would any of you be able to advise me how to generate MT103 in XML2 message formate with LAU (Local Authorisation) using ECC6.0?

Thanks in advance for your help

Regards
