Since users and their actions are the data used to create your overall company statistics, deleting a user will affect all your company data, including data and statistics obtained in the previous time frame.
Deleted users and user data cannot be recovered.
Info
Disabled (passive) users are listed.
If you want to delete your users and their data, you must first deactivate the users you want to delete. You can deactivate your users from the Personnel Management page by clicking the "Deactivate" button next to the relevant personnel.
