To view the details of the System: Error item type, choose Open from the File menu in the Oracle Workflow Builder, then connect to the database and select the System: Error item type or connect to a file called wferror.wft in the <ORACLE_HOME>\wf\Data\<Language> directory.
The System: Error item type contains the following item attributes:
Error Activity ID
Error Activity Label
Error Assigned User
Error Item Type
Error Item Key
Error User Key
Error Message
Error Name
Error Notification ID
Error Result Code
Error Stack
Error Monitor URL
Timeout Value
Event Name
Event Details
Event Message
Event Key
Event Data URL
Event Subscription
Error Type
Error Details
Administrator Role
Subscription Details
Parent Notification Subject
Parent Notification Message Name
Parent Notification ID
Parent Notification Message Type
Parent Notification Recipient Role Name
Parent Notification Recipient Role Display Name
Parent Notification Responder Role
Parent Notification Responder Role Display Name
Error Notification Recipient Role
These item attributes are referenced by the function, notification, and event activities that make up the error processes called Default Error Process, Retry-only, Default Event Error Process, Default Event Error Process (One Retry Option), and Error Process for Notification Response Processing.
Important: If you create a custom error handling process in your own item type, Oracle Workflow automatically sets the above item attributes when it calls your error handling process. If these item attributes do not already exist in your process, Oracle Workflow creates them at runtime. However, if you want to reference these item attributes in your error handling process, such as in a message, you must first create them as item attributes in your process's item type at design time using Oracle Workflow Builder.
