Missing operation for soapAction [] and body element []

Hello,
I am running a Mock Service using SOAP UI 3.0.1
When I am running the Service inside the SOAP UI, it is successful. But when I Sync it is Siebel, it starts giving my an error message.

Here are the contents of log file
Mon Jul 04 07:47:12 CEST 2011:ERROR:com.eviware.soapui.impl.wsdl.mock.DispatchException: Missing operation for soapAction [/CRM/System/Siebel/HistSegmenEmpres/pd_HistSegmenEmpres] and body element [{http://www.vodafone.es/SIEBELSchemas/HistSegmenEmpres.xsd}HistSegmenEmpresRQ] with SOAP Version [SOAP 1.1]
