iStore does not have a shipments notification event. This would be handled by Shipping. See: Shipping Execution Workflows and Oracle
Workflow User's Guide.
For iStore you can modify the messages for notifications -
The Oracle Workflow item type iStore Alerts Workflow (IBEALERT), in the data store file IBENOTIF.wft, contains all Oracle iStore notifications and their messages and
Oracle iStore does not allow customization of notification events. Customers can only customize the notification messages -- steps in the iStore documention -
Oracle® iStore Implementation and Administration Guide Release 11i (Part No. B13549-01)
34.4 Customizing Oracle iStore-Oracle Workflow Integration
You can choose to use only the seeded messages for Oracle iStore notifications. If
you want to create additional messages -- see steps starting on page 34-14
Deborah Bourgeois, Oracle Customer Support
There is change in requirement we just need to implement one type of notification that goes to customer once the shipping is started.
That notification says to user like ..Your Order has been shipped and contains Tracking number.
This would be outside of iStore and after the order has been placed. Therefore, this would be handled by the Shipping Execution.
Seeded iStore order related notifications:
• Order Confirmation - Normal
• Order Confirmation - Next steps for faxed orders
• Orders Not Booked Notification
• Cancel Order
• Return Order Confirmation
• Return Order Approval Notification
• Return Order Rejection Notification
