The change history allows you to track which user changed metadata or profile pictures for a file/asset or object at what time. It shows the time period during which the metadata was edited, as well as previous and new metadata entries.
If the change history is activated for your user role, you will find the "Change History" menu item under the respective module in the detail view when you open a file/asset or object.
Note: Entries always refer to single objects, not multiple ones. The change history can be configured for standard and customized modules.
Changes to metadata can also be made via the system or via customized workflows. These types of entries are marked as "system processes".
