Viewing XML Integration Schemas To view XML, select the Generate Schema/View XML action from the Select Action menu in the following applications: T Enterprise Services T Invocation Channels T Object Structures T Publish Channels You also can view XML on the Web Service Library tab in the Web Services Library application. Integration Schemas Key Fields The following circumstances dictate whether the system generates XML schemas: T Publish channels publish an object structure T Invocation channels facilitate the invocation of an external service T Enterprise services process an object structure as input or output T Object structure services process an object structure as input or output T Standard services process an object, MboSet, MboList or specific individual typed parameters as input or output The input and output types for all services, except standard services, are reusable, as they are based on the object structure for the service. The generated schemas identify the key fields within a service or channel from the object structure definition and data dictionary definitions for the corresponding object. XML schema annotation identifies these fields. For example, the ITEMNUM is a key field in the MXITEM object structure schema. It is indicated as follows: ITEMNUM is a key field You can use the schema to determine the fields that are required to process an inbound XML message. Integration XML and Schemas 77
