EWM overview

Business ExampleWith the introduction of Extended Warehouse Management (EWM) as a second WM application, it is important to understand the background and key characteristics of

EWM so that you can differentiate EWM from the SAP ERP Warehouse Management application.


WM vs. EWM 

The SAP ERP warehouse management system remains a viable alternative for many warehouses. The introduction of the SAP Extended Warehouse Management System does not mean that it replaces the SAP WM system. It just means that there is now an additional alternative for those warehouses that require the functionality provided by EWM.

 Difference  One of the main differences between the SAP WM system and the SAP EWM system is that functionally, the WM system in more .inward. focused. In general, there is very little functionality that provides a link to external processes such as transportation cross-docking, contract packaging and transportation.
