Thanks!
I used "Web service protocol" and with these, looks like they worked:
web_service_call( "StepName=getUniqueRepByNcid_101",
"SOAPMethod=InterfaceService|InterfaceServicePort|getUniqueRepByNcid",
"ResponseParam=response",
"Service=InterfaceService",
"URL={pEndPoint_stg}",
"ExpectedResponse=SoapResult",
"Snapshot=t1405321622.inf",
BEGIN_ARGUMENTS,
"ncid={pNcid}",
"contextNcid={pContextNcid}",
"dbEnv=d",
"withSolr=false",
END_ARGUMENTS,
BEGIN_RESULT,
END_RESULT,
LAST);
I will try with the "'soad_request'. Do you know there is a easy way to have LR generate the code instead?
