Access rights to the routine 449 Personal Details Audit Trail should be defined in the Adonis Control Centre for a user who should be allowed to view Audit Trail information.
By default, this functionality is not enabled for not superusers.
About
Audit Trail tab/view was implemented to have a possibility to track changes made in main personal fields.
Every time a user changes personal details information, a corresponding record is added to the database.
So, all the changes that were made with detailed information about who and when made them can be viewed here.
Data that were changed in the Personal, Employment, and Seniority sections are painted grey, so it is possible to quickly find what was changed and what was not.
Also, you can see by whom it was modified, Trail/Session ID, and the action itself (updating, deleting).
