To efficiently create a cargo, and link them with CoAs, you can create a cargo based on a CoA Template. The CoA Templates are the template cargoes that are maintained in the CoA module.
Open the Cargoes module from the menu on the left.
In the top right corner, click Create .
Select Create New Cargo From CoA Template.
In the modal, select a CoA template to create the new cargo. The fields that are pre-filled are the ones that were filled in when creating the CoA itself, which the new cargo will inherit.
Click Create.
The modal is now draggable, making it easier to see the information "behind" the modal. Hover over the title or the top of the modal to activate it.
Looks and works quite similar to Create Voyage From Template.
