The Commodity Code Rules node defines the commodity code default selection rules used by the Select Commodity Code Dialog. This node contains all the default values that the software is to use. There are two nodes for the commodity code defaults, one for the contractor commodity codes and one for the industry commodity codes.
If you do not have anything in your Commodity Code Rules node, you can load two workbooks to use as a starting point. These workbooks are delivered in the [Product Folder]\CatalogData\PDSTranslator\Bin folder and are named Contractor Commdity Code Rule.xls and Industry Commodity Code Rule.xls. See Piping Specifications Tab (Options Dialog).
