The Ports (or Port Rotation) field lists by default load ports and thereafter discharge ports in the order they were entered irrelevant of actual voyage rotation pattern order. Extra ports displays in the order entered and according to what side of the port call type divider they were placed, i.e. if entered amongst load ports they display amongst load ports and vice versa. Each entered port call displays display as individual rows, each row containing relevant port call data. Port calls can be sorted into actual rotation order (i.e. rotate port call order) in the Ports (or Port Rotation) field, but will, if for example an additional cargo and/or ports are added, revert to default listing. To avoid this the port rotation can be protected, i.e. fixed, despite changes being made elsewhere in the calculation which would otherwise affect. Any new port calls must then be manually added to the Ports (or Port Rotation) field.
Example:
Cargo1: Kandla/Vadinar-Singapore, Cargo 2: Mumbai/Hong Kong,
The Port Rotation field displays in default order (load ports first, discharge second): Kandla (L)-Mumbai(L)-Vadinar (D)-Hong Kong (D)-Singapore (D).
Actual voyage rotation: Kandla (L)-Vadinar (D)-Mumbai(L)-Singapore (D)-Hong Kong (D).
