Issue with Consuming C4C WSDL in ECC System

Hi,

I have developed SOAP Web Service(on Custom BO) in C4C SDK(QA system), downloaded WSDL & Successfully tested in SOAP UI.

Want to consume this C4C WSDL in ECC system.

My C4C landscape has:                         C4C QA --> C4C Production.

My ECC Landscape has:  ECC Dev-->   ECC QA --> ECC Production.

we don’t have a connection between ECC Dev and C4C QA systems, but we have ECC QA to C4C QA.

So how can I develop ABAP Service Consumer Proxy in ECC Dev system.???

I still tried to create Service Consumer proxy in ECC Dev..

T.Code: SE80 --> Package -->Create -->Enterprise Service -->Service Consume -->External WSDL -->Local file -->wsdl upload -->Transport/Prefix --> Complete.

Getting the following error..

Proxy generation: error occurred

Exception occurred in communication framework:Unknown Transport Protocol. C:\C4C\WSOUT.wsdl (Local file path).

Exception of class CX_SLIB.

Please help me on the best approach to consume C4C WSDL in ECC for this landscape.

Thank you in advance,
