Which Salesforce Objects Don't Support History Mode?
Salesforce objects where you have enabled field history tracking are not compatible with history mode. The Salesforce field history tracking feature already records changes and creates a corresponding object with the suffix History.
For example, if field history tracking is enabled for the ACCOUNT object, Salesforce creates a corresponding AccountHistory object. As a result, enabling history mode provides no additional value.
Other objects that do not support history mode include:
- Metadata tables, which have the suffix
_mdt. - Tables without incremental or modifiable columns.
- Tables with an incremental column that is not sortable.
- Tooling API objects, such as
EntityDefinition,FieldDefinition,ExternalString, andExternalStringLocalization.
