You can manifest cargo to provide and update relevant information for inbound cargo, enabling N4 to efficiently and accurately record the cargo details. When you manifest cargo accurately, you provide the terminal as much information as possible prior to the arrival of the cargo. This reduces the time it takes to receive and process inbound cargo, thus increasing the terminal capacity and throughput.
You can manifest cargo to a carrier, such as a vessel or a rail, or you can manifest cargo to a container. You can manifest a cargo lot using the Actions menu from the:
Cargo Lots view (on page 1)
Bill of Lading Inspector (on page 1) 
Items tab Bill of Lading Item form (on page 1) Cargo Lots tab
Unit Inspector Cargo Lots tab
Vessel Inspector Cargo Lots tab
Train Inspector Cargo on Board tab
Railcar Visit Inspector Cargo on Board tab
In addition, you can manifest cargo lots using SNX. The <position> element, which is a child element of the <cargo-lot> element, represents the position of the cargo lot. N4 manifests the cargo lot based on the <cargo-lot> element and the <position> element.
When you:
Manifest Cargo to Container (on page 1): You indicate that the cargo lot is inside a container. In this case, N4 does not create a new unit, instead it associates the cargo lot with the existing unit ID. You can then strip the cargo lot from the unit.
Manifest Cargo to Vessel (on page 1): You associate the cargo lot with a vessel visit and indicate that the cargo lot is on board a vessel at the specified position. In this case, N4 creates a new unit on board the vessel at the specified position. You can then unload the unit from the vessel.
Manifest Cargo to Rail (on page 1): You associate the cargo lot with a train visit (or a railcar visit) and indicate that the cargo lot is on board a train at the specified position or railcar ID. In this case, N4 creates a new unit on board the train. You can then unload the unit from the train.
