If you are sending Shipments (856) via EDI to your trading partner, you may need to provide a Carrier Code (SCAC), Free form ship method, or a service level code depending on the trading partner you are dealing with.
To make things easier and prevent the supplier from keeping track of all those codes and different shipping methods a one time map to the attached list of codes will allow you to send the appropriate code to your trading partner.
When submitting a shipment, the code should be provided in the "ClassCode" field under "ShipmentInfos"
The "CarrierCode" field will be used to directly map a SCAC code. This is the standard established the National Motor Freight Traffic Association (NMFTA). It is recommended to always send us this, if it isn’t provided logicbroker will automatically populate this (if the trading partner requires) in the EDI based off of what was received in the “ClassCode"
