A change history is a record of all changes made to a asset over time and updates every couple of minutes.
The change history for a technical asset can be accessed in the same manner as for a technical asset type. Navigate to and choose the desired asset. Then follow the identical procedures outlined in the documentation: Change history for technical asset types. Adding, editing and deleting field values are audited, as well as changes to relationships and adding responsibility overrides. The deletion of an asset itself cannot be viewed in the asset change history because you will not be able to access the change history page.
