The columns you see and the order they are displayed is determined by the access to
the object's column set. The object values displayed in columns in the List Edit window can be configured to be viewable, editable, mandatory, or read-only. Some objects
may be configured to be only viewable by a specific role but may be editable by another
role. You might not have access to columns due to the column set access set for your
role.
For more information on your role's access to editing values in columns, contact
your system administrator.
