Inventory Management in Oracle Fusion Cloud SCM ensures optimal inventory levels by tracking stock movement, availability, and replenishment needs across warehouses and supply chains. It monitors quantities on hand, in transit, and on order, using real-time data to prevent overstocking or stockouts. For instance, if a product's stock drops below a reorder point, the system triggers a replenishment alert. Option A is incorrect-reducing supplier costs is a procurement goal, not Inventory Management's focus, which is stock optimization. Option B is wrong as it manages warehouse stock, not just supplier shipments. This function balances inventory costs with service levels, supporting efficient operations and customer satisfaction by ensuring products are available when needed without tying up excess capital.
