This design document provides details for configuring SAP's CO-PA (Profitability Analysis) module to support analyzing profitability by market segment. Key configuration decisions include using costing-based CO-PA for flexibility, defining one operating concern for the global setup, and sourcing data for the contribution margin scheme from other SAP modules like sales and production. The design focuses on flexibly defining value fields, profitability segments, and performance measures to automatically collect and report revenues, costs, and sales deductions from business transactions processed in SD and other modules.
