You can achieve planning only for specific resources in Advanced Planning (PP/DS) by using a resource group. A resource group is a collection of resources that share the same characteristics and can be used interchangeably for production. You can assign a resource group to a product or a production version, and then use the resource group as a selection criterion in the planning board or the product view. This way, you can restrict the planning to only those resources that belong to the resource group. References: SAP S/4HANA Manufacturing for Planning & Scheduling - Implementation Guide, page 25; [SAP S/4HANA Production Planning and Manufacturing Certification Guide], page 79.

• Run PP/DS heuristic for repetitive manufacturing: PP/DS (Production Planning and Detailed Scheduling) is a component of SAP S/4HANA that provides advanced planning and scheduling functions for complex production scenarios. You can run the PP/DS heuristic for repetitive manufacturing to automatically assign planned orders to production lines based on the available capacity, material, and sequence constraints. The PP/DS heuristic also optimizes the line utilization and minimizes the setup times and costs.
• Assign planned orders manually in the planning table: The planning table is a graphical tool that allows you to view and manipulate the production plan for repetitive manufacturing. You can assign planned orders manually to production lines by dragging and dropping them in the planning table. You can also adjust the start and finish dates, quantities, and sequences of the planned orders. The planning table shows the capacity situation and the material availability for each production line.

You cannot plan both quantities and capacities during line loading in repetitive manufacturing by using the following options:

• Run MRP with quota arrangement: MRP (Material Requirements Planning) is a process that calculates the quantity and timing of material requirements based on the demand and supply situation. You can run MRP with quota arrangement to distribute the total requirements for a material among multiple sources of supply, such as vendors, plants, or production lines. However, MRP does not consider the capacity constraints or the sequence dependencies of the production lines, and therefore cannot plan the capacities during line loading.
• Assign planned orders manually in the planning table: This option is identical to option C and therefore cannot be a correct answer.

You can select the following standard item categories inside a bill of material (BOM):

• Variable-size item: This item category is used for materials that have variable dimensions, such as pipes, wires, or fabrics. The system calculates the quantity of the variable-size item based on the formula and the dimensions entered in the BOM. You can also use the variable-size item to define a scrap percentage for the material.
• Non-stock item: This item category is used for materials that are not managed in inventory, such as consumables, services, or subcontracting items. The system does not create any reservations or stock movements for the non-stock item. You can use the non-stock item to trigger purchasing requisitions or purchase orders for the material. References: Bill of Material Item Category; Bills of Material in Production Planning
