Production planning is generally done from budgeted sales plan. Planning is based on the Sales plan to meet the sales requirements as per the production cycle times. Demand for the Product is entered through demand management in the form of planned independent requirement (PIR). This data from demand management becomes the input to Material requirement planning (MRP).MRP checks for the availability of various raw materials used for production at different stages using the master data such as Bill of material (BOM) and available current plant stocks.
Material requirements planning (MRP) is a system for calculating the materials and components needed to manufacture a product. It consists of three primary steps: taking inventory of the materials and components on hand, identifying which additional ones are needed and then scheduling their production or purchase.

MRP is the system most companies use to track and manage all of these dependencies and to calculate the number of items needed by the dates specified in the master production schedule. To put it another way, MRP is an inventory management and control system for ordering and tracking the items needed to make a product.
MRP is essential to the efficiency, effectiveness and ultimately the profitability of a manufacturing operation. Without the right raw materials and components on hand, manufacturers can't hope to keep up with the demand for products at the optimal cost and quality. They will also be less able to respond to fluctuations in demand by adjusting production.
To address these shortcomings of MRP, many manufacturers use advanced planning and scheduling (APS) software, which uses sophisticated math and logic to provide more accurate and realistic estimates of lead times. Unlike most MRP systems, APS software accounts for production capacity, which can have a significant impact on availability of materials.
The seeds of MRP were planted early in the 20th century with the development of new models for optimizing manufacturing. In 1913, American production engineer Ford Whitman Harris developed the calculation known as economic order quantity, the amount that minimizes the cost of ordering and storing a good. Concurrently, the mass-production system implemented by Henry Ford showed the value of having strict controls over the flow of materials through an assembly line. Another key driver of industrial efficiency came from the scientific management theories of Frederick Taylor, which included techniques for production planning and control and for improving the efficiency of material handling.
It wasn't until the 1960s, however, that the field got its modern name. That's when a small group of influential engineers championed an integrated system of computerized planning they dubbed material requirements planning. In 1964, IBM engineer Joseph Orlicky developed and formalized MRP after he studied the Toyota Production System, which was the model for the lean production methodology. Then, in 1967, Orlicky's IBM colleague, Oliver Wight, co-wrote a book on production and inventory control with George Plossl, a mechanical engineer and management consultant. The three continued to collaborate and today are usually cited as the pioneers of MRP.
It's important to note that MRP and lean production are not the same, despite their connection in Orlicky's pioneering work. In fact, they are considered by many practitioners to be antithetical, though some say MRP can help with lean production. MRP is considered a "push" production planning system -- inventory needs are determined in advance, and goods produced to meet the forecasted need -- while lean is a "pull" system in which nothing is made or purchased without evidence of actual -- not forecasted -- demand.
An extension of MRP, developed by Wight in 1983 and called manufacturing resource planning (MRP II), broadened the planning process to include other resources in the company, such as financials, and added processes for product design, capacity planning, cost management, shop floor control and sales and operations planning, among many others.
The overall planning process starts with the independent requirements. The demand program, which has to be covered by the production planning in the plant / MRP_Area, is determined using planned independent requirements from a demand forecast, sales orders or stock transfer requirements.
Sales orders can be used as exclusive requirements sources (make-to-order production), or, together with planned independent requirements, they can create the total requirement.Consumption with planned independent requirements is also possible.
While the basic production planning functions are available in the SAP S/4HANA Digital Core ERP-PP (MRP, CRP) embedded PP/DS provides additional advanced options for Production Planning and Detailed Scheduling.
If all prerequisites regarding basic settings and customizing are fulfilled and the master data required for planning is integrated from ERP of SAP S/4HANA Digital Core to embedded PP/DS the production planning in PP/DS can be executed.
Pegging should not be confused with the net requirements calculation: During planning, using the net requirements calculation, the system identifies shortages in order to then create receipts to remove these shortages. If the MRP has taken place, a pegging network will be established based on it.
These include the time situation of operations on resources, the time-based development of the resource load or pegging relationships. Numerous planning activities are executed with the help of the planning board. The result of the planning does not have to be adopted by production. It can also be saved as a simulation version at first.
The Optimization allows to optimize the production dates/sequences and the resource assignment of existing operations/activities that were previously generated by the production planning run or manual planning.
The Alert Monitor is a monitoring Tool that provides the planner pointed information and access to problem situations in production planning in ePP/DS. The purpose of the Alert Monitor is to inform the planner of exception. It is also possible to send alerts by mail.
Do you know if all features from APO are migrated to S4? For example, reschedule a specific Production order will integrate with all others Production Orders updating the planning? And if is possible define prioririty to a specific Production Order or to a PO from a client when reeschduling?
I do appreciate the effort required to write a 1000+ pages book, and it was not my intention to undervalue that. I also accept the book can be a good general reference and starting point for SAP PP, maybe, as Caetano said, a bit more focused on the production control side.
Production planning and control manages and schedules the allocation of human resources, raw materials, work centers, machinery, and production processes. It finds the most efficient way to produce finished goods with the lead times needed to meet production demand.
Production planning helps manufacturers work smarter by efficiently managing internal resources to meet customer orders or demand. It solves what, when, and how much to produce. It establishes production capacity and identifies what raw materials, bill of materials, or alternate bill of materials are needed to meet demand. Then it prepares a workable production plan.
Production control monitors production and measures performance, providing visibility and reporting. If any corrective action is needed it gets initiated. It includes different control techniques to achieve optimal levels of production performance.
Production Planning and Control is the core of any manufacturing unit. It includes material forecasting, master production scheduling, long-term planning, demand management, and more. The planning process kicks off with demand forecasting of a product. Using that forecast data and internal resources available, the production plan is created.
Production planning and control ensure the resources for production are ready when needed. Materials, equipment, and labor must be available at the right time to keep production optimized. It is the central part of a manufacturing business. The larger a business gets, the more PPC becomes essential for a smooth-running operation.
Relevant information from various sources helps to develop a production plan. For instance, data from sales on order quantities and promised delivery dates. Product specifications from the engineering department may also be needed. The planning step helps to keep a streamlined approach to the production process.
Also known as expediting, follow-up locates fault or defects, bottlenecks, and loopholes in the production process. In this step, the team measures the actual performance from start until the end and then compares it with the expected performance.
