Demand planning is an important process for supply chain management across businesses and has a significant impact on the overall efficiency of business operations. Demand planning in SAP APO is therefore, one of the most widely used modules.

The book revolves around a business scenario that requires demand planning design through SAP APO implementation. The scenario is realized progressively in chapters along with relevant concepts, business rationale, links to demand planning process flow, and the design.

The contents have been crafted for easy reading, learning, and practical application with the help of screenshots and illustrations. We recommend that readers simulate the business scenario in their SAP APO system using step-by-step procedures in the book to maximize their learning.

The book begins with an introduction to SCM and its key concepts in covering supply chain planning and execution, challenges and trends, an introduction to the major SCM solutions in the marketplace, and how they enable SCM processes.

explains how SAP APO enables SCM functions. The content focuses on SAP APO after an introduction to the different SAP SCM components and their functionality. We then briefly explain the business processes and functionality for different SAP APO modules. We also explain the SAP APO technical architecture and its integration to peripheral system.

explains the business scenario that elaborates on the business context, challenges, and how APO DP could be a solution.

explains the overall demand planning process flow that illustrates the design and deployment aspects of demand planning, including the integration of DP with APO BW and ERP. Each of the related processes/design is put onto blocks representing a uniform concept. Each of the blocks is explained in the chapter progressively with its relevance to the business scenario.

Chapters 58 explain the detailed design in APO BW, ERP, and APO DP in accordance with the overall demand planning process flow and the example business scenario. We also explain the concepts and business rationale for the choice of a specific design.

In , we explain the APO BW design that lays the foundation for gathering and loading sales history to APO DP.

In , we explain the design in ERP through configuration, master data, and transactions that enable integration between SCM and ERP for APO DP.

In , we explain the basic and foundational design in APO DP and in Chapter 8, we explain advanced design in APO DP, i.e., forecast profile, alert profiles, and macros.

Finally, we provide a set of appendices to complement the contents in the book and application of the learning on an SAP APO system. We have also included data in the appendix relating to the business scenario for its use in developing the design in the SAP APO system.

The book contents will serve the interests of beginners, who wish to understand and apply demand planning; as well as experienced professionals who want to enhance their knowledge of demand planning in SAP APO.

The sequel to this book is called Demand Planning with SAP APO Execution that builds on the contents in this book and covers the execution aspects of APO DP. We recommend that our readers to refer the sequel book to complete their APO DP knowledge.

Demand Planning (DP) is a key supply chain planning function that integrates and interacts with other functions of supply chain management (SCM) on continuous basis. This chapter focuses on explaining SCM in general to facilitate the context of understanding DP as we progress through the chapters of this book. This chapter focuses on both the general understanding of SCM from business perspective and SCM as an IT solution.

We will begin by introducing SCM and its key aspects in terms of supply chain planning, supply chain execution, challenges, and trends. Additionally, we will briefly mention major SCM solutions that exist in the marketplace and how they benefit SCM in business.

Supply Chain Management (SCM) is a key lever for most companies because it is one of the aspects that determine competitiveness. SCM is more relevant in the current climate in which circumstances are more dynamic and have more uncertainties than ever before.

In this chapter we explain SCM, as SCM forms the context and reason for Demand Planning; in other words, proper demand planning contributes to SCM. Demand planning itself does not operate in isolation in respect to other supply chain functions as it is continuously impacted by the other functions in the supply chain. Therefore, in order to focus and understand demand planning it is essential to understand SCM; because it is in this SCM space that demand planning makes its mark (i.e., takes inputs and provides outputs back to SCM). To ensure successful demand planning, we need to be sensitive to the factors in the supply chain that can potentially impact demand planning and consequently, supply planning as companies continue to struggle to adjust supplies and production in highly volatile market dynamics. We will, therefore, dedicate this chapter to SCM for your generic understanding.
