Message Schema Validation
Validating messages against message schemas can ensure that during integration development no changes or deletions were inadvertently made to a message. You can use schema validation on outbound and inbound messages.
During runtime schema validation, PeopleSoft Integration Broker checks messages to ensure that the XML structure is valid according to the specified message schema. If Integration Broker encounters a service operation with a message structure that does not adhere to the specified message schema, message delivery fails and Integration Broker generates an error message.
Schema validation is based on the message schema for the message.version defined on the default service operation.
You can view any schema validation error details on the source application server, using the Asynchronous Details page or Synchronous Details page in the Service Operations Monitor.
When schema validation is enabled the structure of a message cannot be changed.
