we are using the WSDL of the SAP SolMan (SAP version of Service Desk ) web service.

When we want to open a ticket we need to have multiple childs of the same "xpath" in the SOAP message (as permitted by the WSDL). If you load the WSDL into the integration activity you can only use ONE child element in the pre-mapping. Reading through some Cool Solutions I found that it should be possible to add further child elements in the Integration tab of the workflow. But selecting "Add Child" in the Input XML does nothing (no add, no error). If I edit the XML by hand may changes are not saved.
