You can limit the validity of a BOM by plant and by period. The plant determines the organizational area of validity for the BOM, and you can assign the same BOM to different or further plants if the prerequisites are met. The period of validity for a BOM is restricted by the valid-from date and the valid-to date in the BOM header and item, which determine when the BOM becomes effective and when it ends. References: Validity of Bills of Material, BOM Item Validity

 In reorder point planning, the system compares the available stock with the reorder point to determine the net requirements. If the available stock falls below the reorder point, the system triggers a procurement proposal for the material. The quantity of the procurement proposal depends on the lot size procedure that is defined in the material master. The lot size procedure determines how the system calculates the order quantity based on factors such as demand, costs, and storage space. There are different types of lot size procedures, such as static, periodic, or optimum lot size. References: [Production Planning with SAP S/4HANA], page 156; [SAP Help Portal: Lot Size Calculation].

Phantom assemblies are assemblies that have their own product structure, but whose assembly does not actually physically exist. The components of the phantom assembly are incorporated directly in the superordinate product. The product structure of the superordinate product contains a reference to the phantom assembly. You can use phantom assemblies for the following purposes:

• To simplify the structure of bills of material: Phantom assemblies allow you to group components that belong together logically or functionally, without creating an additional level in the product structure. This can make the product structure easier to maintain and understand.
• To reduce the number of material masters: Phantom assemblies do not require a material master record in SAP S/4HANA, as they are not physically produced or stored. This can save storage space and reduce the effort of creating and updating material masters.
• To reduce the number of changes required in bills of material: Phantom assemblies can be used to represent common subassemblies that are used in multiple products. This way, you only need to maintain the product structure of the phantom assembly once, and any changes will be reflected in all the products that reference it.

Phantom assemblies do not increase the number of planning levels, as they are not considered as separate planning objects. They also do not make the assignment of components easier, as the components are assigned to the superordinate product, not to the phantom assembly. References: Phantom Assembly | SAP Help Portal, Phantom Assembly | SAP Help Portal, Planning Phantom Assemblies | SAP Help Portal.

MRP (Material Requirements Planning) is a process that calculates the quantity and timing of material requirements based on the demand and supply situation. MRP performs a net requirement calculation for each material, which compares the available stock and the planned receipts with the requirements and the planned issues. MRP takes into account the following elements during net requirement calculation:

• Safety stock: The minimum quantity of material that should be maintained at all times to avoid stockout situations due to unforeseen fluctuations in demand or supply. MRP considers the safety stock as a requirement and tries to replenish it whenever it falls below the defined level.
• Purchase orders: The confirmed orders from external vendors that are expected to be delivered within a certain time frame. MRP considers the purchase orders as planned receipts and reduces the net requirement by the quantity and date of the purchase orders.

MRP does not take into account the following elements during net requirement calculation:

• Forecast key figures: The projected demand for a material based on historical data, trends, and other factors. MRP does not consider the forecast key figures as requirements, but as a basis for creating planned independent requirements, which are then considered as requirements.
• Maximum stock level: The maximum quantity of material that should be maintained at any time to avoid overstocking and excess inventory costs. MRP does not consider the maximum stock level as a constraint, but as a target value for the lot-sizing procedure, which determines the optimal quantity and frequency of replenishment orders.

 If the operation of a production order is dispatched, the DSPT Dispatched status is set for the operation. This means that the operation has been assigned to a resource and scheduled with a start and end date and time. The options to reschedule the operation are as follows:

• You can reschedule the operation using finite scheduling in a planning table. Finite scheduling considers the capacity availability of the resources and the dependencies between the operations. You can use the planning table to manually drag and drop the operation to a different time slot or resource, or use the automatic dispatching function to optimize the scheduling of the operation. Finite scheduling updates the DSPT status and the dates and times of the operation.
• You can reschedule the operation in the Manage Production Operations app. This app allows you to view and edit the production orders and operations in SAP S/4HANA. You can change the start and end date and time of the operation, as well as the resource, in the app. However, the app does not check the capacity availability of the resources or the dependencies between the operations. Therefore, you need to ensure that the changes are feasible and consistent. The app updates the DSPT status and the dates and times of the operation. References: Identifying the Basic Principles and Tools of Capacity Planning; SAP Help Portal

A reduction strategy is a method of shortening the lead time of an order by reducingcertain time elements in the order scheduling1. The time elements that can be reduced by a reduction strategy are move time, wait time, and queue time2. Move time is the time required to move a material from one operation to another. Wait time is the time between the end of an operation and the start of the next operation. Queue time is the time before an operation can start at a work center due to the work center’s capacity utilization3. These time elements can be reduced by a percentage or a fixed value in the reduction strategy. References: 1: Reduction Strategy | SAP Help Portal(https://blog.sap-press.com/4-strategies-for-make-to-stock-production-with-sap-s4hana) 2: 4 Strategies for Make-to-Stock Production with SAP S/4HANA(https://blogs.sap.com/2022/03/22/highlights-for-manufacturing-in-sap-s-4hana-2021-part-2-production-planning-engineering-operations/) 3: Scheduling | SAP Help Portal(https://blogs.sap.com/2022/04/26/manufacturing-in-sap-s-4hana-cloud-planning-strategies/).

A resource network is a business object in PP/DS that defines the allowed directed connections between two or more resources. A directed connection means that the connection from Resource 1 to Resource 2 is not the same as the inverse connection from Resource 2 to Resource 1. You use this object to model existing production constraints more precisely, with the objective of creating a finite and technically feasible production schedule. Resource networks simplify the modeling of resource restrictions for consecutive operations or orders1

A resource selection is a business object in PP/DS that defines the criteria for selecting a suitable resource for an operation or an order. You use this object to specify the characteristics, attributes, and capacities of the resources that can be used for a particular production process. Resource selection allows you to optimize the resource utilization and reduce the setup times and costs2

A resource matrix is a business object in PP/DS that defines the relationships between different resources based on their characteristics and attributes. You use this object to determine the setup times and costs for changing from one resource to another. Resource matrix allows you to model the setup effort and expense more accurately and improve the production efficiency3

A resource hierarchy is a business object in PP/DS that defines the structure and sequence of resources that are used for a production process. You use this object to represent the logical and physical dependencies of the resources and to control the scheduling and sequencing of the operations or orders. Resource hierarchy allows you to model the production flow and capacity more realistically and ensure the technical feasibility of the production plan.

• 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.
