Name
Employee name is 100 characters at most. Different employees may have the same name, but employee codes should not be identical. In case two employees have the same name, there are two ways to solve the problem: 1. Add a number behind the name(for example: Tom 1, Tom 2), 2. Input different codes in edit property.
