Oracle Workflow also provides access protection for business event and event subscription definitions, in order to protect Oracle seed data and preserve your customizations in an upgrade. In the Business Event System, access protection is based on a customization level assigned to each event and subscription. The customization level determines who can update the event or subscription definition.
An event or subscription can have one of the following customization levels:
Core - This level is used only for events and subscriptions seeded by Oracle. At this level, you cannot make any changes to the event or subscription definition. However, any property in the definition can be changed by an Oracle seed data upgrade.
Limit - This level is used only for events and subscriptions seeded by Oracle. At this level, you can update the event or subscription status to Enabled or Disabled, but you cannot make any other changes to the object definition. Conversely, an Oracle seed data upgrade cannot change the status setting, but can change any other property in the definition.
User - This level is automatically set for events and subscriptions that you define. At this level, you can change any property in the event or subscription definition. However, an Oracle seed data upgrade cannot make any changes in the definition.
During an Oracle E-Business Suite seed data upgrade, the Workflow XML Loader loads Business Event System object definitions in normal upload mode, preserving any customized data according to these customization levels. See: Using the Workflow XML Loader.
