Cost Rollup in Oracle Fusion Cloud SCM aggregates all cost components-material, labor, and overhead-to calculate the total cost of a product. This process rolls up costs from raw materials through production stages, providing a comprehensive view for pricing and profitability analysis. For example, producing a widget might involve $5 in materials, $3 in labor, and $2 in overhead; Cost Rollup totals this to $10 per unit. Option B is incorrect because it excludes materials and overhead, which are integral to the process. Option C is false-Cost Rollup reflects current costs, not fixed values, adapting to fluctuations like material price changes. This function supports accurate financial reporting, cost control, and strategic decision-making by revealing true production costs.
