For certain types of publications, such as a Buyer's Guide, the products and services sold by the advertiser are listed as part of the advertisement. Products/services are identified by a category code and an optional subcategory code, as well as by a brand name. A description can also be entered.
Often, the advertisers and exhibitors that an organization deals with are the same company, but some organizations want to keep the products/services identified for advertising orders separate from the products/services identified for exhibition orders. To support this, two flags exist in the Cus_Product table: DEFAULT_TO_SHOWS_FLAG and DEFAULT_TO_ADV_ORDERS_FLAG. When products/services are copied into an advertising order line, products/services where DEFAULT_TO_ADV_ORDERS_FLAG = 'Y' are automatically copied.
