Which table is the parent table for IndependentDemand?

The parent table for IndependentDemand is the DemandOrder table. In the context of supply chain management and inventory systems, IndependentDemand typically refers to the demand for finished goods that is not driven by the demand for other items. It is often forecasted based on market trends, historical sales data, or customer orders.

The DemandOrder table serves as the primary source for managing and tracking these independent demands. It records specific orders made by customers or stock replenishments that are not dependent on subcomponents or assemblies, which distinguishes it from other demand types that rely on parent-child relationships, such as dependent demand driven by production schedules.

In contrast, the other tables mentioned, such as SupplyOrder, ScheduledReceipt, and ForecastOrder, fulfill different roles within the overall inventory management system. For example, SupplyOrder relates to the materials and products that suppliers provide based on orders, while ScheduledReceipt captures the timing of inventory arrivals, and ForecastOrder focuses on anticipated demand based on statistical models rather than firm customer orders. These distinctions clarify why DemandOrder is classified as the parent table for IndependentDemand.
