Key Components
Customer master data in SAP ECC is organized into several logical areas that allow different departments to maintain relevant information while sharing one consistent customer record.

- Company code data such as reconciliation accounts, payment terms, and dunning procedures.
- Sales area data covering pricing, shipping conditions, sales organizations, and partner functions.
- Tax information, currencies, customer classifications, and credit-related settings.
- Business rules that support invoicing, reporting, and regulatory compliance.
