Getting no active Web Service with operation error siebel service

[arunpandi984353]

Hi, 

I am getting below error from siebel service when I try to integrate siebel soap service from APIGEE. The backend is soap service(Siebel service) and the service is working fine when we try in SOAP UI but while doing the integration with APIGEE we are getting below error.

We have noticed that _Input is adding extra path value soap action in the actual service which causing this issue. We checked the code multiple time and no where we are not adding extra path value(_Input) 

Actual service url format:           

Error message:

<siebelf:errorstack>

                        <siebelf:error>

                            <siebelf:errorcode>SBL-EAI-04313</siebelf:errorcode>

                            <siebelf:errorsymbol>IDS_EAI_WS_OP_NOT_FOUND</siebelf:errorsymbol>

                            <siebelf:errormsg>There is no active Web Service with operation named &apos;http://siebel.com/CustomUI:Create Corporate Customer Process Flow_Input&apos;.(SBL-EAI-04313)</siebelf:errormsg>

                        </siebelf:error>

                    </siebelf:errorstack>

Please advise on this issue
