SAP WM vs SAP EWM – Why Businesses Must Migrate Now 

What is SAP WM 

SAP Warehouse Management (WM) is a powerful software module that automates and controls all warehouse processes, from receiving goods to shipping orders, providing real-time inventory visibility, optimizing storage, and streamlining logistics for better efficiency, cost reduction, and accuracy in high-volume operations. It manages inbound/outbound movements, inventory tracking, picking, packing, and integrates with other SAP modules like Sales & Distribution (SD) and Material Management (MM) for seamless supply chain operations. 

What is SAP EWM 

SAP EWM (Extended Warehouse Management) is a powerful SAP module for managing complex warehouse operations, providing automated support for inventory, goods movements (inbound/outbound), picking, packing, and shipping, integrating seamlessly with other SAP SCM solutions to optimize warehouse efficiency, space, and labor for high-volume logistics. It offers detailed control over storage, processes like cross-docking, yard management, and even labor, enhancing transparency and cost reduction across the supply chain.
