SAP C_TS422_2023 Exam Questions

The planning strategy settings in the Capacity Scheduling Table determine how the system schedules the operations or orders on the resources. You can select the following settings:

Finiteness level: This setting defines how strictly the system considers the capacity availability of the resources when scheduling. You can choose between infinite, finite, and optimized scheduling. Infinite scheduling ignores the capacity availability and schedules the operations or orders as early as possible. Finite scheduling respects the capacity availability and schedules the operations or orders only in the free slots of the resources.Optimized scheduling tries to find the best compromise between infinite and finite scheduling by minimizing the delays and overloads12

Scheduling control: This setting defines how the system handles the scheduling conflicts that may arise when scheduling the operations or orders. You can choose between rescheduling, shifting, and splitting. Rescheduling means that the system moves the conflicting operations or orders to a later date. Shifting means that the system moves the conflicting operations or orders to another resource within the same resource network.Splitting means that the system splits the conflicting operations or orders into smaller parts and schedules them on different resources or dates13

Direction: This setting defines the direction of the scheduling. You can choose between forward and backward scheduling. Forward scheduling means that the system schedules the operations or orders from the start date to the end date.Backward scheduling means that the system schedules the operations or orders from the end date to the start date14

Backward scheduling is a method of determining the order dates for components from dependent requirements by starting from the requirement date of the finished product and working backwards through the production structure. Backward scheduling considers the following time elements:

Operation duration: This is the time required to perform an operation on a resource, such as a work center or a machine. Operation duration is influenced by various factors, such as the quantity, the lot size, the setup time, the processing time, the teardown time, and the operation scrap. Operation duration is subtracted from the requirement date of the finished product to determine the start date of the operation.

In-house production time: This is the time required to produce a material in-house, from the start of the first operation to the end of the last operation. In-house production time is influenced by various factors, such as the routing, the work center, the production version, and the scheduling margin key. In-house production time is subtracted from the start date of the first operation to determine the order start date of the material.

Backward scheduling does not consider the following time elements:

Total replenishment lead time: This is the time required to procure a material externally, from the creation of the purchase requisition to the receipt of the goods. Total replenishment lead time is influenced by various factors, such as the planned delivery time, the goods receipt processing time, the release time, and the scheduling margin key. Total replenishment lead time is used in forward scheduling, not backward scheduling, to determine the order dates for externally procured materials.

Planned delivery time: This is the time required to deliver a material from the vendor to the receiving plant. Planned delivery time is maintained in the purchasing info record or the material master record. Planned delivery time is a component of the total replenishment lead time, which is used in forward scheduling, not backward scheduling, to determine the order dates for externally procured materials.Reference:Backward Scheduling | SAP Help Portal,Scheduling | SAP Help Portal,SAP S/4HANA Production Planning and Manufacturing Certification Guide, page 77-78.

Pegging is a term used in Advanced Planning to describe the relationship between the receipt and the issue elements of a product within a location. Receipt elements are planning elements that increase the stock of a product, such as production orders, purchase orders, or stock transfers. Issue elements are planning elements that reduce the stock of a product, such as sales orders, planned independent requirements, or reservations. Pegging links the receipt and issue elements according to the bill-of-material structure of all related products and represents the material flow through all levels of production. Pegging enables the system to identify and display quantity and date/time problems, such as shortages or delays, and to forward scheduling changes to other dependent elements.Pegging also forms the basis for the availability check and the capacity check in Advanced Planning12.

Make-to-stock production (10) is a planning strategy that supports the production of a finished good based on a forecast and without any reference to sales orders. This strategy is used when the finished good has a stable and predictable demand, and the company wants to maintain a certain level of safety stock to meet customer orders. If customers order more than the forecasted quantity, this does not affect the production program, as the system does not generate any additional planned orders or purchase requisitions for the finished good. Instead, the system reduces the planned independent requirements by the sales order quantity, and the excess demand is covered by the safety stock or the available stock. This strategy allows for a smooth and continuous production process, and avoids frequent changes in the production plan.Reference:Make-to-Stock Production | SAP Help Portal,Planning Strategies | SAP Help Portal,SAP S/4HANA Production Planning and Manufacturing Certification Guide, page 52.

A reduction strategy is a method of shortening the lead time of an order by reducing certain 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.Reference: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/).
