WSDL Import Restrictions Importing a WSDL to create a Business Object Model is not supported in the following circumstances: • The WSDL to be imported has more than one output part. Business Object Model operations can have only one return type. • The XML schema has import restrictions, as outlined in XSD Import Restrictions. • The WSDL is invalid. In each of these cases the import does not complete and a dialog is displayed summarizing the error.
