For inbound loads you can schedule a dock appointment. For voyages or containers, this is not possible.

However, often there is a mixture of regional/national incoming containers and international ocean transport containers.

Landed cost is only used for the latter category. Dock appointments are now limited to Purchase order, Load and Sales order.

Proposed solution: add to the enum Reference type (TMSAppointment.ApptRefType) the Voyage and the Voyage container with relations to these landed cost tables.
