Draw a <Timeout> transition from a notification activity to some other activity to force the process to perform the other activity if the notification activity does not complete by a specified period of time. See: To Define Nodes in a Process.
When an activity times out, Oracle Workflow marks the activity as timed out and then cancels any notification associated with the timed out activity. The Notification System sends a cancelation message to the performer only if the canceled notification was expecting a response and the performer's notification preference is to receive e-mail.
Note: If you are using the version of Oracle Workflow embedded in Oracle Applications, you can optionally use the WF: Mailer Cancellation Email profile option to prevent notification mailers from sending any notification cancelation messages. See: Setting Up Notification Mailers, Oracle Workflow Administrator's Guide.
Processing then continues along the <Timeout> transition as indicated by your process definition. If a timed out activity does not have a <Timeout> transition originating from it, Oracle Workflow executes the error process associated with the timed out activity or its parent process(es). See: To Define Optional Activity Details.
Note: You must have a background engine set up to process timed out activities. See: Setting Up Background Engines, Oracle Workflow Administrator's Guide.
