This document provides guidance on setting up transportation management in Dynamics AX 2012 R3, including defining rate bases, rate masters, shipping carriers, and other necessary configurations to calculate cost-effective transportation rates for moving loads from one location to another for both inbound and outbound scenarios. The setup process involves initializing base engines, defining modes of transport, load templates, terms of delivery, mileage and transit time engines, rate masters using break masters, and assigning accessorial charges and constraints to shipping carriers. Proper configuration of these transportation management features in AX allows for optimization of transportation costs.
