The Web services access operation uses the Web services connector that you created in the New Web Services Connector wizard to invoke Web services.
Creating a Web services access operation involves creating data mappings between the IBM® WebSphere® Multichannel Bank Transformation Toolkit data model and the Web services data model. Data mappings must be created so that the Web services provider is able to receive and process data sent from the WebSphere Multichannel Bank Transformation Toolkit operation context.
