If you intend to generate the data mappings through the Generate Web Service Access Operation wizard immediately after you create the Web service connector, you must make sure that you define the data and the context of the UDTT business operation in the Transaction editor before you create the Web service connector.

For more information on defining the data and the context in the Transaction editor, refer to the sections on defining data and context in the Transaction editor guide.

If you do not intend to create data mappings immediately after you create the Web service connector, you do not need to define the data and the context of the UDTT business operation before the Generate Web Service Access Operation wizard is launched.
