Replenishment Planning (C)in Oracle Fusion Cloud SCM ensures optimal inventory levels by predicting demand and adjusting supply plans proactively. Using forecasts—e.g., expecting 300 units next month—it triggers replenishments to maintain stock (e.g., ordering 250 units when levels hit 50), avoiding overstock or shortages. Option A (Cost Accounting) tracks costs, not inventory levels. Option B (Supplier Qualification) evaluates suppliers, not stock planning. Option D (Manufacturing Execution) manages production, not replenishment. This feature balances cost and availability, reducing waste (e.g., $5,000 in excess stock) and ensuring service continuity.
