SAP LES / SAP WM
Warehouse management with SAP Logistics Execution System (SAP LES) and SAP Warehouse Management (SAP WM)
SAP LES is the tried-and-tested solution that is fully integrated into SAP ERP. This complete integration is and remains the big advantage of SAP LES / SAP WM in comparison with SAP EWM. Business bookings in ERP can trigger follow-up processes in warehouse management directly. If installed centrally, the interface between SAP ERP and SAP WM is merely a logical interface.
For a long time, decentralised SAP LES / SAP WM solutions were recommended for performance-intensive warehouse management and/or warehouse control processes. The performance of centralised ERP systems is now, however, usually so good that a centralised implementation of SAP LES / SAP WM for controlling manual and automated warehouse systems is possible. If, however, a decentralised solution is needed for some reason, careful consideration is needed, as SAP EWM may then be the better option.
