Proxy INTERFACE_SIGNATURE_ERROR namespace problems

Hi All,

Scenario: 3rd party -> PI 7.4 -> Inbound Proxy on ECC

The error message I am getting is INTERFACE_SIGNATURE_ERROR (Information about the method parameters is missing for the interface). From what I have read this is because the sender and receiver namespaces are different. An OSS note describes the situation http://service.sap.com/sap/support/notes/1714297

I don't really want to use the same namespace for the sender and receiver. If I add a mapping then the above error does not occur but the mapping is pretty useless.

Is there anyway to change namespace delivered to the inbound proxy so it matches that of the receiver?

Thanks

Che
