You use the Production Planning and Detailed Scheduling (PP/DS) feature:
To create procurement proposals for in-house production or external procurement to cover product requirements
To optimize and plan the resource schedule and the order dates/times in detail
You can take the resource and component availability into account here. Above all, PP/DS is used to plan critical products, such as products with long replenishment lead times or products that are produced on bottleneck resources. You can use PP/DS to create executable production plans and:
Reduce lead times
Increase on-time delivery performance
Increase the throughput of products and reduce the stock costs, through better coordination of resources, production, and procurement
You transfer the planning-relevant data such as master and transaction data (for example, sales orders and stocks) from SAP S/4HANA to PP/DS. You plan the critical products in PP/DS and transfer the planning results to SAP S/4HANA. In SAP S/4HANA, you execute order processing for manufacturing orders and, if necessary, plan the uncritical products. You manage the stocks here too.
You use PP planning procedures to specify which planning action the system executes for each product, if a planning-relevant event occurs for a product in PP/DS or in SAP S/4HANA. For example, the system can immediately automatically plan the product or write a planning file entry for the product when there is a change in requirement.
You use the production planning run to execute heuristics, detailed scheduling functions, or optimization for a large number of objects online or as a background job. During the production planning run, several heuristics or functions can be executed one after the other. In a production planning run, you execute procurement planning in particular for products with planning file entries (net change planning).
You can use interactive planning for important products that you wish to plan manually or to solve any planning problems that have arisen during automatic planning. Various tools are available for interactive planning, such as the detailed scheduling planning board or the product planning table.
Detailed Scheduling schedules orders automatically on the resources, taking various planning conditions into account (such as the component or resource availability).
Using the optimization tool, you can optimize the resource schedule according to certain criteria, such as setup times and setup costs, to improve the planning situation and solve particular detailed scheduling problems.
PP/DS uses pegging to create relationships between the stock, receipt, and requirements elements of a product within a location. Based on these relationships, the system can identify quantity and date/time problems and forward date/time changes to other BOM levels.
Access the Alert Monitor
Display exceptional, unexpected, or critical situations in the PP/DS planning process. You can define which alerts you would like the system to generate and display.
Cross-industry and industry-specific solutions
PP/DS supports various processes across industries (for example, make-to-order production or make-to-stock production) and production types (for example, shop floor production, repetitive manufacturing, or process manufacturing). In addition to the standard solutions, industry-specific solutions are available. For more information, see PP/DS Repetitive Manufacturing, Extended Orders, and Project Manufacturing and Make-to-Order Manufacturing.
