How do I sync in-app notifications for all users in Fusion Applications?

Run the Synchronize Notifications in Global Header scheduled process on a regular basis. The process removes notifications from the global header older than 30 days, as well as all notifications acted on elsewhere, for example, by email or by other approvers.

You need the Manage Scheduled Job Definition (FND_MANAGE_SCHEDULED_JOB_DEFINITION_PRIV) privilege to run this process.

1. In Scheduled Processes, click Schedule New Process.
2. Leave the type as Job.
3. Search for and select Synchronize Notifications in Global Header.
4. Use the Advanced option and schedule the process. It’s recommended to run every two hours. You can run more often depending on the volume of approvals, but never more often than every 30 minutes.
5. Submit the process.

The process might take hours to finish if it's running for the first time or if it hasn't been executed for an extended period of time.
