"SAP EWM firms have the ability to control warehouse processes and manage movements in the warehouse, mitigate problems and issues with enhanced warehouse efficiency, and transform operations into an adaptive fulfillment supply chain that can share its resources." SAP EWM is similar to SAP WM functionality, but with more flexibility in building objects like warehouse structure, picking, putting away, HU (handling unit), RF, and more.[2] Also, activity areas, work centers, and resources are elements incorporated into SAP EWM that are new additions since SAP WM. SAP WM was the company's first foray into a specific Warehouse Management Solution.
