You might want to create an empty source or target definition if you have a WSDL that defines a large number of elements and you do not want to include all elements in the definition. For example, you might 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.
To import a source or target definition from a WSDL without creating XML views, select the Do not create XML views option 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 columns, and the relationship between views.
