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.

The MRP planning file is a list of all materials relevant to the planning run. The system sets an entry in the planning file for a material when there is a change that affects the material requirements planning, such as changes to stock, requirements, receipts, or MRP data in the material master. The following processes lead to an entry in the MRP planning file:

• Changing the procurement type in the product master, which determines how the material is procured (internally or externally) and affects the MRP procedure and lot-sizing procedure.
• Changing the stock in inventory management, which changes the stock/requirements situation of the material and triggers a net requirements calculation.
• Changing the purchasing contract in materials management, which creates a purchase requisition as a receipt element and affects the availability of the material. References: Planning File, Planning File Entries for MRP Areas, SAP Exam C_TS422_1909 Topic 10 Question 10 Discussion

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.
