In RemOnline, you can manage the access rights of employees to your customer database. To do this, go to the "Settings > Employees" page and select the role of the employee for whom you want to restrict the rights.
You can read about the access rights of an employee in the Clients section here.
The access rights in the Work Orders section also include the following right:
Can view the client info — allows seeing the client in work orders. If the right is disabled, the employee can only see information about the asset in the work order. There will be no column with information about clients in the Work Order Table.
Set permissions for employees according to your needs.
