Create your own Fiori push notifications

There is a “bell” icon in the Fiori Launchpad. All Fiori push notifications are displayed here. The aim of this wiki article is to enable you to display your own notifications there. The prerequisite is that the technical setup and configuration has been carried out in the system.

Overview of the required objects and customizing

• Creation of Y/Z notification class
  • Interface /iwngw/if_notif_provider
  • Implementation method /iwngw/if_notif_provider~get_notification_parameters
  • Implementation method /iwngw/if_notif_provider~get_notification_type
  • Implementation method /iwngw/if_notif_provider~get_notification_type_text
  • Implementation method /iwngw/if_notif_provider~handle_action
  • Implementation method send_notification
• Customizing
  • Register notification provider
  • Manage notification provider

Creation of Y/Z Notification class

For method send_notification you have to consider which parameters are required. Also the success/error handling.

Necessary customizing

Register notification provider

Use the “Register provider” button to register the notification provider. A name for the provider, e.g. “YMM_...” and the created provider class are assigned here.

Note'

The created entries are created in the respective logged-in system language (time of creation of the wiki article for release 2023). This means that if the customizing entry was made in German, it will not be visible when EN logs in. The language to be used for customizing should be agreed in the project.

Manage notification provider

Perse the provider is not activated, which is why you still have to activate it.
