Understand how change event processing works, then evaluate if full collection or applying changes will be the best option for your environment.
To apply changes, select Data Sources > Applications or Application Definitions, collect data and publish, then apply changes. Note that the option to apply changes might not always be available. Identity Governance evaluates the collection scenario and makes a determination regarding the ability to perform change event collection.
You can hover the cursor over each status icon on the Application Sources and the Application Definition Sources pages to see the current status of your action. Click the date and time link to view more details about the current collection.
