When you import a source or target definition from a WSDL and you want to manually define the XML views and ports, you can create an empty source or target definition.
For example, you have a WSDL that defines ten elements in the input message but you want to include only two of the elements in your source definition. You can create an empty source definition and manually define the two elements. The target definition is not affected. You can import the target definition and create the XML views.
To import a source or target definition from a WSDL without creating XML views, select Do Not Generate XML views in Step 2 of the import process. After you create an empty source or target definition, use the WSDL workspace to define XML views and ports, and the relationship between views. Right-click the title of the source or target definition and select WSDL Workspace.
