Proxy in BPM

Hi,

I am doing a BPM which has proxies. In SAPR3 side, I have defined inbound interface for proxy generation in a namespace. But in XI interface mapping, I am using target message to R3 as Abstract interface which has message type defined in different namespace. When generation of proxy, how can I link message type in XI to message type in R3.

There is an xml namespace in message type. There I have given sap message type namespace for XI message type. And the message type names in XI and SAP are same.Is this the right way to link?

Thanks,

Deno
