 The time element of midpoint scheduled operations that can be reduced by reduction strategy settings while dispatching are teardown time and setup time. Teardown time is the time required to dismantle the production equipment after the operation is completed. Setup time is the time required to prepare the production equipment before the operation is started. Both teardown time and setup time can be influenced by the reduction strategy settings, which define the percentage of reduction and the minimum duration for each time element. The reduction strategy settings can be maintained in the work center or the routing. The system applies the reduction strategy settings when dispatching the operations to the resources in the planning board or the product view. References: SAP S/4HANA Manufacturing for Planning & Scheduling - Implementation Guide, page 32; [SAP S/4HANA Production Planning and Manufacturing Certification Guide], page 81.

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.

You can exclude a material from the MRP run by using a specific material status or a specific MRP type. A material status is a user-defined indicator that can be assigned to a material master record to control the procurement and planning activities for the material. For example, you can define a material status that blocks the material from being planned by MRP. An MRP type is a parameter that defines how a material is planned by MRP. For example, you can use the MRP type ND (No Planning) to exclude the material from the MRP run.
