The user who has the security group “Help operator” assigned (how to assign particular security group to the user please look to chapter 4 User administration) can modify system field labels.
Figure 135 Labels editing
Note that the user with the security group “Help operator” assigned can modify labels in the system windows that he has access to. E.g. system administrator will not be able to edit labels of payment transaction window, because he does not have access to this window. In this case system administrator should additionally assign “Cashier” security group to himself to be able to access payment transaction window and then he can change the labels.
