Tracking Source Changes
This topic describes the change events and change event details that the system tracks out-of-the-box. Because the change tracking functionality is highly configurable, the out-of-the-box options might differ from those in your system.
Change Events
The system automatically tracks source changes based on the following events:
When you update a source
When you update a source specific to a season
When you add a source to a product
When you add a source to a season
When you remove a source from a product
When you remove a source from a season
When you change the lifecycle state of a source
Change Event Details
The system tracks change event details, including designated attributes, for the following source change events:
Update (including season specific information)
Add (to product or season)
Changed source attributes, including source to season attributes if applicable, appear when you expand the related change event on the Tracked Changes tab. The table lists the name of the attribute that has been changed, as well as the original and updated attribute values, and is sorted alphanumerically based on the changed attribute name.
