Field permission can be enabled or disabled
per entity on role. For each setting
you can enable or disable Visible and Editable separately. If Editable is enabled Visible setting is not in use, user can then always both
view and edit the field.
For each entity you can enable or disable all fields in
entity at the same time on top level. If you expand the list for an entity you
can enable/disable fields individually. Click the small arrow symbol in front of entity name to expand the list.
Top level showing a yellow symbol
means that permissions in the list are
mixed, contains both enabled and disabled field permissions.
Note that when you create a new role, all field permissions are initially disabled.
