In Core, you can edit or customize the security permissions of a user to hide rates from the screens and reports.
To prevent a user (say an employee) from seeing the cost and bill rates:
- Open the Security screen from your company menu > Settings > Security Permissions.
- In the list view, click on the user row whose security you want to edit and select View Details.
- On the Customize Profile > Screens tab, select Employee in the list and uncheck 'Allow Read Rate' to prevent the user from seeing the rates.
- Save this setting.
- You can do this for all the users by editing or customizing the security profile itself and saving it under a new name. All users with that security profile will have the modified setting of the rates.
