Enable Source Tracking in Sandboxes
By enabling source tracking in Developer and Developer Pro sandboxes, Salesforce DX tooling can automatically track new, changed, and deleted metadata components. You can then select and determine which changes to move forward in the development cycle and release. For DX tooling that uses a Salesforce DX project or source control repository, source tracking can aid in conflict detection and resolution. And best of all, because source tracking identifies which metadata components changed, you no longer have to manually keep track of changes.
You can enable source tracking in Developer and Developer Pro sandboxes in two ways: in your production org for all sandboxes created from it, or for a specific sandbox. After you turn on source tracking, you can disable it at any time.
- For all Developer and Developer Pro sandboxes—when you enable the feature in your production org, all newly created and refreshed sandboxes use source tracking. Existing sandboxes don’t have source tracking enabled until you refresh them.
- For a specific Developer or Developer Pro sandbox—if you don’t want to enable source tracking in all sandboxes, or want to enable source tracking without refreshing the sandbox, you can enable it directly in the sandbox from the Sandbox Settings Setup page.
