Routing guide lines contain the specific conditions to use when routing a shipment.
A routing guide can contain multiple routing guide lines.
When routing occurs, the shipment is matched against the routing guide lines. Based on the criteria specified, a carrier and carrier service is selected. The shipment mode is determined for shipments/loads based on the combination of the carrier and carrier service.
When routing results in a change to the shipment destination, the system reroutes the shipment, with the revised destination as the factor for routing. This type of configuration is used for consolidator nodes. While routing the second time, system looks for the routing guide entry that contains destination node, but without any other destination parameters filled out (such as address, etc.). However, the consolidator destination node should be defined.
To create a routing guideline:
When the conditions set are assessed, the routing guide line that matches most conditions is used. For example, imagine there are three routing guide lines:
Routing guide line A - What to do when shipping from Massachusetts
Routing guide line B - What to do when shipping from Massachusetts, and when shipping from the zip code 01810.
Routing guide line C - What to do when shipping from Massachusetts or NY.
If the shipment originates from the zip code 01810, it matches all of these routing guide lines. The actions specified in Routing guide line B is used, as more conditions are met (both the state and the zip code).
If the shipment originates from Massachusetts, but not from zip code 01810, then both Routing guide line A and Routing guide line C match.
