# Edit an Entry Source

After you configure an entry source, you can edit it or review its configuration before activation. After activation, you can review the entry source configuration, but you can’t edit it. To edit an active entry source, pause or stop the Journey and then create a new version.

![Important](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_journeys_and_automations-264-0-0-production-enus/e08cdd71-c1c1-4ae5-a5e9-8a6dad583ad4/images/icon_important.png)

Important Don’t modify a data extension that is used as the entry source in an active journey. When activated, the journey uses a snapshot of the entry source data extension. Fields added after activation aren’t detected by the running journey. If you must add a new field to the entry source data extension, create a new version of the journey to include the updated data extension. For example, you can add a field to allow you to use personalization in messages within the journey.

If a Journey Builder Audience (Email Studio, Automation Studio, or MobileConnect) was created before January 2018, it now appears on the canvas as a data extension entry source. Click the entry source icon in a running journey to view its previous configuration. Its icon matches its previous configuration, so journeys with Email Audiences appear with the same icon, but their label reads **Data Extension**.

![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_journeys_and_automations-264-0-0-production-enus/e08cdd71-c1c1-4ae5-a5e9-8a6dad583ad4/images/icon_note.png)

Note You can't edit the object a Salesforce entry source uses to decide who enters the journey. To choose a different object in a Salesforce Data, Campaign, or Experience entry source, delete, and recreate the entry source.

1. In a draft journey, hover over the entry source or its schedule.
2. Click the entry source or schedule.
3. To reach the step you want to edit or view, click **Back**.
4. Save the edited entry source and journey, if necessary.
