Password field encryption in XI

Hi All,

My scenario is RFC -> XI -> Web service.

Web service method requires parameters like user id, password, etc. I pass these parameters from my RFC (request payload). Can somebody tell me, how to encrypt these fields in XI so that user viewing sxmb_moni can not see these fields in request/response payloads.

Or if there is some other approach to achieve this, can somebody explain me that?

Thanks & Regards,
