webservice - The service operation requires a transaction to be flowed

Hi,

I am using vugen 11.52 Build 5113

we need to create web service using WSDL URL for create operation. this service uses webservice Atomic transaction. You can find the script snapt shot and output below.

while running the script we are getting the error response -  The service operation requires a transaction to be flowed. Request you to pelase share your feedback on fixing this error

WCF - Custombinding has been set as sceario type in Manage service setting.

web_set_user("Doamin\\Username","*******","Host:Port"); 

web_service_call( "StepName=SomeCreateService_101",
        "SOAPMethod=BizTalkServiceInstance|WSHttpBinding_ITwoWayAsyncVoidTxn|SomeCreateService",
        "ResponseParam=response",
        "Service=BizTalkServiceInstance",
        "ExpectedResponse=SoapResult",
        "Snapshot=t1422532201.inf",
        BEGIN_ARGUMENTS,
        "xml:Create="
            .....,
        END_ARGUMENTS,
        BEGIN_RESULT,
        END_RESULT,
        LAST);

Output:
