This activity code is used to define the maximum number of weight ranges in the price list lines.
This parameter depends on the complexity of the carrier price lists found, but in general it should be in the region of 10 to 20.
This criterion has an impact on the database, where the characteristics of the weight ranges (PLIMAX, PLIBKT, and PLIUOMRND fields) are the fields with multi-occurrences in the BPCARRIER table.
The BPY code, which is used to define the maximum number of region codes that can be used, and the SPC code, which defines the maximum number of links between the postal code roots and regions, are the other activity codes sizing the carrier price lists.
