Use this tab window to specify schedule line types. When creating a supplier schedule and its schedule lines, you can specify whether the schedule line should be converted into a purchase order line or whether it should be used as planning data only. The supplier schedule line type to use on schedule lines is determined by the schedule template when schedules are generated. Schedule line types are connected to the schedule template periods. Note that one schedule line type is inserted during installation of the system, PD/Past Due Lines of the Backorder type. There must always exist at least one schedule line type of the Backorder type; however, by creating other Backorder line types with other identities, the PD line type can be removed.
