Understanding Lookup Type Setup

If the system must calculate a rate using two variables, then you must set up the definitions for the two variables. You specify the lookup types or variables before you enter the values. The first lookup type can be based on any number of factors, such as weight, specific distances, zones, prices, or number of pieces as defined in Lookup Type table (49/BM). You then must specify the number of entries for lookup type one.

For the second lookup type, you specify the type as defined in Lookup Type table (49/BM) and specify the number of entries. After you define the lookup types, and the system creates a table, you must specify the numeric values at each point in the table.

For example, assume that you must set up a rate based on carrier zones and weights. The first lookup type defines each of the zones. The second lookup type defines different weights at which the system determines the rates. After you define the two lookup types, you enter the numeric values in the table. Then, if you have a three-pound shipment with a destination of zone 2, the system uses the table to find the exact freight charge for a package of that criterion.

Note: For LTL (Less Than Truckload) rating in the United States, the system enables you to set up deficit weight rates and look-ahead rates. For deficit weight rates, the rate level must be detail, the rate basis must be weight, the detail level must be NMFC, and the first lookup type must be weight.
