Leveraging these features can unlock SAP EWM’s full potential, enhancing operations, inventory tracking, and the supply chain.

Choosing Between SAP WM and SAP EWM

Deciding between SAP Warehouse Management (WM) and SAP Extended Warehouse Management (EWM) depends on the warehouse size and complexity, as well as specific operational needs.

SAP WM is suitable for operations with high volumes and complex supply chains. It efficiently manages goods movement, inventory, and distribution. It enhances warehouse operations, boosts inventory accuracy, and streamlines logistics processes.

However, SAP will stop supporting SAP WM by 2025. Therefore, businesses using SAP WM should consider transitioning to SAP EWM for continued support and the latest features.

SAP EWM offers more than SAP WM, including additional tools like labor management and internal routing. EWM is highly scalable and integrates seamlessly with other SAP components, making it ideal for managing larger warehouses and complex supply chains.

With EWM, companies can achieve higher operational efficiency, real-time insights, and superior customer experiences. It helps reduce operational time and meet market demands effectively.

Businesses should consider their warehouse size, complexity, growth plans, and need for advanced control tools when choosing between SAP WM and SAP EWM. This ensures selecting the best SAP warehouse system for their needs.
