The Statistical number or Statistical goods code is used to print Intrastat reports. You only need to enter Statistical Goods Codes for parts that are bought or sold within other EU countries.
You can create a table over statistical goods codes that are used in the system in the Statistical Goods Codes procedure in the Global Settings module. You can obtain a list over Statistical Goods Codes for different products, according to the current statistical goods list, the Combined Nomenclature (CN) from your customs authority.
If you have set the parameter Include part's statistical number on customer orders?, under the Extra info button in the Update Customer procedure, then the Statistical number will be printed as a text row for this part on quote rows, order rows and invoice rows.
