DRP only plans items designated as distribution items. Usually, one site supplies these items to another site. To designate a distribution item, set its Purchase/Manufacture code to D in Item Master Maintenance (1.4.1), Item Planning Maintenance (1.4.7), or Item-Site Planning Maintenance (1.4.17). Item-Site Planning Maintenance lets you define an item as a distribution item at one site and a non-distribution item—that is, a manufactured or purchased item—at another.

See User Guide: QAD Master Data for details on defining items.
