Overtime amount calculation in freight invoice
The calculation considers the Overtime Rate (OR), the Overtime Days (OD) and the actual port days in the voyage port were the service is delivered.
The amount is calculated as:
If OD = 0 OR OD > days in port, then Amount = OR X Port days
If 0 < OD <= days in port, then Amount = (OR X OD / Port days) X Port days
