Can't use WSDL for proxy

Hi,

I have scenario for proxy to SOAP Asycn. For SOAP we have WSDL provided by 3rd party which has request structure

To avoid mapping, i used the request structure as Inbound & outbound service interface in ESR.

While generating proxy i am getting the fields added with <n0... which is causing the SOAP to reject the content

Can you advice, if i can use the WSDL for creating  inbound & outbound service interface or i should create separate Data type for request from ECC.

PS: The only reason why i am using WSDL for both is since the SOAP structure is deeply nested & would be time to create it.
