How does tracking by master bill of lading work?

This article explains what data will be returned to you when tracking by only a master bill of lading

The Vizion Ocean Freight Visibility API tracks containers on a container level no matter the input. When tracking a shipment with only the master bill of lading number Vizion will identify all containers associated with the bill of lading, create a reference for each, and provide updates for each container's active or most recent journey.
