SAP EWM (Extended Warehouse Management)

Most companies these days have some kind of product or service for their customers. Manufacturing goods and products require a lot of manpower. Apart from that, a lot of logistical operations are associated with it. Plus, the warehouse where these goods are stored has also evolved from being simple storage spaces. They are now high-end distribution centres where many logistical operations take place.

Thus, companies focus a lot on warehouse management. This is important for optimizing and controlling the different warehouse functions. These include tracking inventory of goods, managing new stock, and handling shipping orders. So, companies need powerful software for warehouse management.

This is where SAP EWM makes its way. It is a part of the SAP Supply Chain Management package. But the software is also available outside the SCM package and consists of apps for warehouse management. In this article, we will dive into the details of SAP EWM.

SAP EWM was initially launched as a successor to the Logistics Execution Warehouse Management platform. This consisted of added benefits of labour-management and material flow system. In 2008, the SAP EWM 5.1 was launched with a material flow calculator. Then in 2009, the 7.0 version was released which had Merchandise Distribution Cross Docking, which helped to reduce the gap between production supply.

A major step was taken in 2013. SAP combined the Extended Warehouse Management (EWM), Transportation Management (TM), and Event Management (EM) in version 9.0 of SAP EWM. This helped companies to empower their supply chain and logistics operations. In 2016, SAP included the EWM functionality into the SAP S/4HANA suite.

The Embedded EWM was launched in SAP S/4HANA 1610. This allowed users to utilize the processing power of SAP HANA, thus reducing the total cost of ownership. This was also better than using a decentralized EWM. The special EWM functionality is available to anyone having the SAP HANA license.

The Embedded EWM is great for small and medium-sized companies. If anyone requires additional features, they can purchase a different license.
