Technical Questions
Is there an ability to track and trace logging of changes and deletions?

- Audit Trail Log (project/activity details page) it has the information about changes done to a project/activity and includes information about who did which action and when;

- Security Log (user details page), it is available in the Enterprise edition only and lists all events of changing user password, password expiration, user account lock and expiration due to inactivity, etc;

- the "SYS_BackLog" table in the database, it lists events of deleting projects, activities and time entries with full information about deleted objects including information of who did which action and when.
