Hi experts,  I trying to consume a SOAP service which is implemented in my SAP system. Somehow it's not possible to call the service. I think this has something to do with the   export mapping or the way I'm providing parameters to the service. I created the export mapping based on a web service operation and generate automatically mapping.  The message points out that I want to export an empty object. But isn't the ZDocumentChange03 the object which has the relevant information and provides them to the web service?    I have no idea where I could start the troubleshooting process. Any kind of hints will help me.  Thanks  An error has occurred while handling the request.
