Hi, I'm working in a project where there are a few requirements that need to modify on top of arrival journal, Landed cost > Shipping containers > All shipping containers > Manage > Functions > Create arrival journal.
I notice most of the objects are on ITM model and mainly the classes objects has the 'internal' keyword that make it not extensible. Can I know how can I achieve this? How can I modify the classes and business logic on top of ITM model?
