In order to become globally competitive in today’s dynamic business environment, organi-zations have to come closer to customers and deliver value added services and products in the shortest possible time. The primary business process through which this is achieved is the sales and distribution process. However, the sales and distribution process is just one part of an enterprise resource planning (ERP) system. This chapter will focus on the sales and distribution (SD) process of SAP’s ERP system. This chapter will assist in learning about the basic functions that make up this process and how it affects the other modules in the ERP system. This chapter will also look at the Purchasing process and the materials requirements planning (MRP) process and how all the three processes are linked together to form one complete business process.
