 Planned independent requirements (PIRs) are demand elements that represent the sales or production program for a material. They are used to plan the production or procurement of finished products or assemblies in advance, based on the expected demand from customers or internal sources. Some benefits of planning with PIRs are:

• Reduced delivery times: By planning with PIRs, you can ensure that the required materials and capacities are available when the actual sales orders arrive. This reduces the lead time for fulfilling the customer orders and improves the delivery performance.
• Option to forecast planning for production resources: By planning with PIRs, you can use forecasting methods to estimate the future demand for a material based on historical data and trends. This allows you to adjust the production or procurement plan accordingly and optimize the utilization of production resources, such as machines, labor, and materials. References: [Production Planning with SAP S/4HANA], page 144; [SAP Help Portal: Planned Independent Requirements].

• Increase the capacity supply in a time-phased interval: You can use the capacity planning table or the capacity planning board to increase the available capacity of a resource by changing the shift sequence, the shift duration, or the number of individual capacities. You can also use the capacity leveling function to distribute the capacity requirements over a longer time horizon. This way, you can avoid capacity overloads and create a balanced capacity load.
• Determine a time period with available capacity on the planning board: You can use the planning board to visualize the capacity load and the capacity availability of a resource in a graphical Gantt chart. You can use the filter and zoom functions to focus on a specific time period and resource. You can also use the capacity evaluation function to display the capacity situation in a tabular or graphical form. This way, you can identify the time periods with available capacity and plan the operations accordingly.
• Form optimum sequence to reduce setup times: You can use the setup matrix or the setup group key to define the setup times and the setup categories for a resource. You can also use the setup optimization function to determine the optimum sequence of operations that minimizes the total setup time. This way, you can reduce the capacity consumption and increase the throughput of the resource. References: Identifying the Basic Principles and Tools of Capacity Planning; SAP Help Portal; [SAP S/4HANA Production Planning and Manufacturing Certification Guide], page 82.

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 betweenrescheduling, 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

A production planning run in Advanced Planning (PP/DS) is a process that optimizes the supply and demand situation for a set of materials and locations within a given planning horizon. The possible results of a production planning run are:

• Planned Order: A planned order is a proposal for internal production or external procurement of a material. A planned order can be converted into a production order or a purchase order, depending on the source of supply. A planned order can also be firmed, which means that it is not changed or deleted by subsequent planning runs.
• Production Order: A production order is a document that defines the operations, materials, resources, and costs required to produce a material. A production order is created from a planned order or directly by the user. A production order can be released, confirmed, and settled as part of the production process. References: [SAP S/4HANA Production Planning and Manufacturing Certification Guide], page 181; [SAP Help Portal: Production Planning Run].

Lead time scheduling is a method of scheduling production orders that calculates the start and finish dates of each operation based on the operation duration, interoperation time, and other time elements. The time elements that are relevant for lead time scheduling of a production order are:

• Setup time: The time required to prepare the work center for the operation, such as changing tools, adjusting machines, or cleaning the work area.
• Processing time: The time required to perform the operation, such as machining, assembling, or testing the product.
• Teardown time: The time required to restore the work center to its original state after the operation, such as removing tools, resetting machines, or disposing of waste.
• Interoperation time: The time between two consecutive operations, such as transportation, waiting, or inspection time.
• Float before production: The time buffer before the scheduled start date of the production order, which can be used to compensate for delays or changes in the production plan.
• Float after production: The time buffer after the scheduled finish date of the production order, which can be used to compensate for delays or changes in the production plan.

The opening period and the total replenishment lead time are not relevant for lead time scheduling of a production order. The opening period is a parameter that defines the earliest possible start date of a production order, based on the material availability date and the planning time fence. The total replenishment lead time is a parameter that defines the total time required to procure or produce a material, from the time the requirement is identified until the time the material is available for use.
