Important

- You can extend only standard context definitions.
- You can’t modify inherited standard components such as nodes, attributes, and mappings.
- To maintain data integrity, avoid performing a Sync in production orgs. First, perform the Sync in a sandbox org. Then, export the updated context definition as a package and deploy it to the production org.

1. From Setup, in the Quick Find box, enter Context Service, and then select **Context Definitions**.
2. On the Standard Definitions tab, from the action menu, select the standard definition that you want to extend, click ![Arrow pointing down](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ind-context_service-264-0-0-production-enus/e9dc37f3-cb53-4bc1-be8b-b6873099d0be/context_service/images/context_service_down_arrow_icon.png), and then select **Extend**.
