History

History storage displays the record field changes in all tables in the human-readable format.

Note

You cannot create, edit, or delete records in the History (sys_history) table. Only users with the admin role can read them.

Restore a record

    • select one or several records by checking the box on the left
    • open the record you need
  3. Click Restore.
Info

The restored record will have the attributes described in the JSON field. The system restores the record version as it was before the deletion.


Note

Records are restored independently of each other. For example, if deleting record A causes records B and C to be deleted, and then record A is restored, records B and C remain deleted. They should be restored additionally.
