Assigning Smart Part Numbers to a Product
Smart part numbers defined on a product class are not inherited by the products in the class. You must manually assign the part number generation method to a product.
When you assign a generation method to a product, this method is used for generating part numbers whenever this product is used in new quotes, orders and so on.
To assign a generation method to a product
- Navigate to the Administration - Product screen, then the Product Definitions view. 
- In the Products list, select the desired product. 
- In the final applet, in the product Part Number Method field, enter the generation method information. 
- Click Release to make it take effect.
