Extended Warehouse Management (EWM) offers flexibility in automating various goods movements processes and for managing stocks in complex warehouse. The system supports planned and efficient processing of all processes of goods movement in your warehouse.
EWM gives the ability to map a complex warehouse in detail in the system, providing the visibility of stock, down to the storage bin level. EWM enables you to optimize the use of various storage bins efficiently and can effectively store stock together from several plants in the same warehouse. Using EWM, you can control and optimize various goods movement processes in the warehouse. There are multiple ways in which an EWM solution can be deployed to solve the complex warehouse requirements and challenges. Choosing between these different deployment options of SAP EWM has always been a hot topic of discussion. There are two methods to deploy EWM that can be broadly classified as Embedded EWM or a decentralized EWM solution.
Beginning with 1610 version of S/4 HANA Enterprise Management, SAP has provided the core functionality of EWM solution in SCM system in the digital core of the S/4 HANA system. This method of deployment is known as the embedded EWM solution. This meant that the basic functionalities of EWM such as Inbound, Outbound process, Process Oriented Storage Control (POSC), Layout Oriented Storage Control (LOSC) and Handling Unit Management (HUM) etc. are part of the standard S/4 HANA license.
Main Deployment Options of SAP EWM
Embedded EWM is a suitable model of deployment for small and medium sized businesses with small warehouses with low volume, throughput and lesser degree of warehouse automation. In such cases, business can benefit from the simplified integration of embedded EWM to SAP S/4HANA business processes.
Decentralized EWM on S/4 HANA Platform
Until the release of embedded EWM in S/4 HANA 1610, EWM solution was part of the SAP Supply Chain Management (SCM) server. This version of EWM system was deployed on SAP Netweaver. SAP released the new EWM 9.5 solution on S/4 HANA platform in May 2019, this is the new decentralized EWM solution on SAP’s HANA database. Some of the key features of decentralized EWM on S/4 HANA are listed below,
Decentralized EWM on S/4 HANA platform is suitable for businesses with large volumes of transactions with multiple complex warehouses connected to a single ERP system. With this SAP has moved the decentralized EWM application to the HANA database, which will facilitate to bring in advanced applications such as IoT and machine learning to warehouse application and help in automation of the warehouse processes.
