Hi AXERP,
Microsoft recently acquired a transportation module which will be included in a future release of AX.
Take a look at this post: blog.technologyevaluation.com/.../microsoft-to-acquire-blue-horseshoe-warehouse-and-transportation-management-solutions
If you need the functionality now, you can contact Blue Horseshoe to see if their current solution meets your requirements.
I also have some experience with an ISV vendor called IconAX. They have a very good solution for import and landed costs. To my opinion this solution has the functionality you are looking for.
