What is the Difference Between EWM and WM?

What is SAP WM?

SAP WM Module is basically a warehouse management system designed by SAP for the planning and execution of physical stock management and stock movements in warehouses with shelf management.

SAP WM module is an Enterprise Resource Planning (ERP) module that deals with material flows through the ERP system. It manages the inventory and related costs and provides real-time information on stock levels, movements, and usage.

SAP WM module helps to manage inventory costs by tracking cost of goods sold across several locations of a company. It helps to consolidate costs and charges using location-specific costs or cost allocation rules.

SAP WM is used to:

  • Plan and schedule material movements in the warehouse
  • Monitor actual inventory levels against planned levels
  • Check consignment lot numbers against delivery notes received from external suppliers

What is SAP EWM?

SAP EWM is the version created by enriching the SAP Warehouse Management (SAP WM) solution, one of the most used warehouse management applications in the world, with additional functions.

The SAP EWM solution has been designed to structure and manage the storage of goods in warehouses, distribution centers and logistical centers. Its main purpose is to improve efficiency and performance by automating processes like receiving and storing goods, replenishing stock levels, managing inventory and optimizing space allocation.

SAP EWM offers a broader range of features and functionalities for managing product life cycles and providing a single view of all supply chain processes.

  • Picking orders and packaging orders for shipping;
  • Checking incoming goods against purchase orders;
  • Creating electronic bills of lading;
  • Creating electronic shipping documents;
  • Managing returns and exchanges.

Differences between SAP EWM and SAP WM

If you are looking for a solution to manage your warehouse operations and make them more efficient, then SAP EWM could be an option worth considering. However, before making any decision regarding this matter, it is important to consider some key aspects related to these two solutions.

While both products offer basic functions for managing warehouses and their operations, there are also some differences when it comes to their capabilities. In fact, while SAP EWM offers advanced functionality such as forecasting and replenishment planning, which allows users to develop strategies based on inventory levels and other factors such as lead time or demand rate; SAP WM only provides basic functionality like picking orders or goods receipt control.

SAP EWM is similar to SAP WM in terms of features, but it offers more customization options, such as warehouse structure and picking/putaway processes. SAP EWM also incorporates new ideas such as activity zones, Work Centers, and Resources. 

EWM, according to SAP, is a more robust and versatile alternative to WM. EWM has the same basic core functionalities as WM, but adds features like labor management and internal routing. The WM module will no longer be produced, and its support period will end in 2025, according to the SAP roadmap.
