The SAP SD (Sales and Distribution) module is one of the most important modules in SAP ERP and S/4HANA. It handles all processes related to order-to-cash (O2C), starting from sales order creation to billing and customer payments.
With the transition to SAP S/4HANA, SD has been enhanced with new functionalities, simplified data models, and Fiori apps to make processes faster and more user-friendly.
