ShipmentId. It may include up to 200 items.
If InboundShipmentHeader is set. it replaces the header information
for the given shipment.

the line time to inbound shipment.
For non-existing item, it will add the item for new line item;
For existing line items, it will replace the QuantityShipped for the item.
For QuantityShipped = 0, it indicates the item should be removed from the shipment
