Correct Answer: B
Heuristics are planning functions that execute planning for selected objects, such as products, resources, operations, or line networks, using a specific procedure. Heuristics are used in interactive planning, the SAP S/4HANA Digital Core MRP_live or in the Advanced Planning (PP/DS) production planning run. In the Advanced Planning, you can execute several heuristics, which belong to both production planning and detailed scheduling, for the same products in one planning run. Heuristics can help you to solve planning problems for defined objects, such as creating feasible production plans, scheduling operations, assigning resources, or leveling capacities. Heuristics can also consider various constraints and parameters, such as lead times, lot sizes, setup times, priorities, or alternative modes12.
