The abbreviation SAP EWM stands for SAP Extended Warehouse Management. As the name suggests, it is a warehouse management system with an extended range of functions. Essentially, the SAP EWM system supports the entire warehouse logistics, the processing of all goods movements and warehouse management. The focus is on efficient logistics and warehouse processes.SAP has been a leading provider of warehouse logistics solutions in the past. For a long time, SAP LES Warehouse Management (SAP WM for short) was regarded as the standard for logistics and warehouse management. Since its introduction in 1993, the functionality of the module has been continuously expanded. Numerous extensions in the form of add-ons were also available. Only a few examples are integration options for further functions such as floor conveyor technology, C-parts bearings or machine controls. SAP EWM, introduced in 2005, already has most of these functions on board as standard.In contrast to SAP WM, SAP EWM is not a module, but a completely independent system for the requirements of intralogistics. Companies therefore operate their ERP and SAP EWM on different instances. While ERP is responsible for commercial processes, logistics transactions are handled by EWM. Master data, transaction data and documents for goods receipt and goods issue are exchanged and compared via interfaces. The reason for this separation is to distribute the workload evenly.Since the introduction of S/4HANA, "Extended Warehouse Management" has been integrated into the core of the latest Business Suite ("embedded EWM"). Furthermore, SAP EWM is part of SAP SCE, SAP's Supply Chain Execution Platform.What are the advantages of SAP EWM?The main advantage of SAP EWM lies in the numerous possibilities of process automation for warehouse logistics and warehouse management. For example, it is possible to map distances including steps in order to optimize material flows. The entire process of a product - from goods receipt and quality inspection to the final storage location - can be automated. In contrast to SAP WM, an unlimited number of warehouse types can also be defined with SAP EWM, which is particularly useful for large logistics structures.It is also worth mentioning that SAP EWM is delivered with an open source code. Thus, company-specific adaptations are easily possible. In addition, a functioning SAP partner network has been established in which consulting and development companies offer a wide range of individual EWM functions.What functions does SAP EWM offer?The functional scope of SAP EWM goes far beyond that of the SAP WM module. SAP EWM is suitable for warehouse control even if complex scenarios with several locations are involved. The following functions are particularly noteworthy:Fine-grained storage location management and optimizationMapping of all goods movements, as well as goods receipt and goods issueMapping of work centers in the warehouseinventoryMonitoring and planning of warehouse stocks and goods movementsConnection of data radio (RF connection)Warehouse control (interfaces to automation systems)In the following we would like to take a closer look at these functions.Warehouse Management and Storage Bin Optimization with SAP EWMIn SAP "Extended Warehouse Management" companies have the possibility to map all warehouse facilities. These include automatic high-bay warehouses, block warehouses and fixed bin warehouses of various types. Stocks are managed in SAP EWM at storage bin level, which can be defined individually. Material flows can be tracked precisely at any time thanks to the storage location logic. The localization of individual products is also possible without any problems. SAP EWM automatically optimizes the allocation of storage bins if required. The system uses criteria such as dimensions and turnover frequency.Further information can also
