Pay Code Configuration Merged

The ability to set a pay code as NOT PAYABLE - used for calculation only and not to be displayed on the employee payslip. We have a scheme that uses pension bandings and this has resulted in a payment and offset pay code to correctly calculate the pension contribution, which offset each other and then a pension pay code is displayed detailing the actual deduction. This is a very confusing solution and employees will query this unnecessarily. It should be possible to "hide" pay codes from payslips.
