SMC3 RateWareXL Integration - Product Freight Group , NMFC Freight Class

Hello experts,

To integrate SAP TM with SMC3 RateWare XL, TM needs to send the NMFC freight class to SMC3. The NMFC freight class is determined based on the Product Freight Group in the material master in TM correct?

So my question is, how is the Product Freight Group populated? Is this field populated as part of the material master data CIF from SAP ERP (from the Material Freight Group)? Or is it manually maintained in TM?

Thanks in advance,

Thanks,

Stan
