Summary :
Implementing finite planning in APO with the SAP_MRP_001 heuristic results in suboptimal resource utilization, frequent delivery date violations, and long planning runtimes. The heuristic struggles with finite scheduling due to absent objective functions and setup optimization, leading to inefficient resource utilization and unfeasible production plans. Modifications include net change planning and parallel processing to enhance MRP performance, but gaps in resource scheduling remain problematic, potentially leading to significant planning delays or use of alternative infinite resources, which exacerbates resource underutilization.
