In the top right corner in the Bills of Lading screen, click the createicon. You will then see a modal where you need to enter the required information in order to create a Bill of Lading.
Start typing in vessel name and select from the drop down. Once the appropriate vessel is selected you may select port call from the drop down. The port call drop down will show discharge ports and voyage reference for the selected vessel. Choose the correct voyage/discharge port.

When the required fields are filled in, you select the corresponding sub-cargo(s) from the table, and click create in the Bills of Lading modal.
