The SAP Extended Warehouse Management System (EWM) is the strategic warehouse management software from SAP and, in comparison to the classic warehouse management (WM), offers enhanced functions for complex logistics processes.

Through the decentral approach, as a completely integrated part of the SAP Supply Chain Management platform, the EWM system can be used independently of ERP, whereby the respective processes are linked with each other via interfaces and the process flows can be combined. As a result, there is also the possibility to link the SAP EWM to external, non-SAP systems. With S/4 HANA-Version 1610 EWM will be integrated in ERP.

SAP EWM was developed for the automated control of large warehouse complexes, whereas in classic SAP Warehouse Management (SAP WM) customized enhancements were often necessary. Through the modular construction and conceptual design of SAP EWM, simple structures can be mapped and controlled, as well as large, complex warehouses.

In comparison to SAP WM, the following are among the enhanced components of SAP EWM:

• Process- or layout-oriented creation of warehouse tasks
Integrated control of material flow MFS
Display of logistical value-added services (VAS)
• Use of a warehouse management monitor
Efficient wave planning
Strategies for placement into storage and removal from storage
Handling unit (HU) management

Further development of EWM is of great importance to SAP

Functions that already exist are continuously improved or enhanced and new functions are additionally delivered. For this, SAP has set up its own Customer Connection Programm, where customer requests can be entered and processed.

Extended Functions of EWM

Inbound Goods Outgoing Goods
Shipping Notification: Working with dispatch notification (confirmations) allows the disposition to plan more precisely, because in the period of time between the time of the purchase order and the customer’s desired delivery date, reliable information is transmitted about the delivery that is to be received. Wave Management: EMW items from warehouse requests for deliveries can be combined in waves or grouped or allocated. These waves must be picked and processed at approximately the same time. In EWM, waves can be generated either manually or automatically.
Unloading: Incoming appointments can be planned and managed in SAP EWM. For example, in the goods receipt process, the gate occupancy for unloading can be planned as soon as the vehicle has arrived. When the vehicle passes the control point, it is assigned to a free gate and can be unloaded upon arrival at the gate. Loading / Shipping: The units are sorted and packaged for shipping. In doing so, an actual stock comparison is carried out with the ERP, because this step contains the last possibility to correct the unit before shipping.
Quality Check: The Quality Inspection Engine (QIE) is used in order to check the delivered product for the fulfillment of the previously determined quality criteria. Packaging: In the packaging dialog, products in HUs or individual HUs can be packed into in additional, superordinate HUs.
Deconsolidation: Deconsolidation is the opposite of consolidation and is used to split a handling unit into multiple deconsolidation handling units. This process step is necessary if multiple products are contained in a handling unit that, in the subsequent step, are to be stored in different storage areas. Consolidation: Products that should be taken out of the warehouse are bundled for the shipping process in accordance with certain criteria. Therefore, products from various storage areas are appropriately aggregated for the packaging process.
Stock Placement Strategies: With the help of an automated storage bin search, the appropriate location can be determined for the goods that are to be stored. This is realized using pre-defined stock placement strategies stored in the system.: z.B. Fixed Storage Bin, Free Warehouse, Addition to Existing Stock, Empty Storage Bin, Empty Storage Bin, Block Storage, High Rack Storage Area, HRL or Hazardous Material. Stock Removal Strategies: In SAP, various stock removal strategies can be used or combined for every storage area. The following stock removal strategies are available in SAP EWM: e.g. FIFO (First in – First out), LIFO (Last in – First Out), Expiration date, Batch, Serial numbers, Random access
Production Supplies: EWM uses various processes for the integration of production supplies: Production orders (PP-SFC), Process orders (PP-PI_POR), Serial production (PP-REM), Kanban (PP-KAB)

Integrated EWM Processes

Batch Management Batch management is carried out with the core data in SAP ERP and makes it possible for products to be provided with various characteristics, features, and variations.
Serial Number Handling A serial number is unique for an individual product. With it, it is possible to identify products in a targeted way. This function is applied especially for technological products.
Slotting/Rearrangement Slotting makes it possible to determine product data, with which the storage bin for the products can automatically be determined by the stock placement strategy. Accordingly, it is also the basis for the stock removal strategy.
Resource Management Resource management is integrated with the RF functions and can be used to link warehouse resources, labor, and material handling equipment with the RF environment, so that the correct resources can be assigned to a stock issue.
Cross Docking During cross docking, you transport products or handling units (HUs) from incoming goods directly to outgoing goods, without placing it into storage in between.
Yard Management With yard management, you can monitor and manage vehicles (transport units) that arrive at the warehouse to deliver products.
Kitting A kit is a list of products that is always delivered together. For this, there are the following two options:
1. Kit-to-Stock: The kit is prepared for the stock and stored after completion. A kit can consist of the following levels: Kit Header: shows the finished kit / Kit Component: a product in the kit
2. Kit-to-Order: The kit is created directly for an order – each kit is put together in accordance with a certain customer order.
Handling Unit (Nested HU) A handling unit is a physical unit from products in connection with associated packing materials. EWM also allows development and management of nested HUs, for which individual HUs are packaged in superordinated HUs.
Packing Instructions With packing instructions, individual products or product groups can automatically be assigned a packaging material.
Value Added Services (VAS) The assembly and packaging of products, labeling, kitting, or oiling are part of VAS. Hereby, the inbound and outbound processes in the warehouse change.
Picking Product to Person: Automatic High Rack Storage Area, Automatic Small Parts Storage Area, Etc.
Person to Product: Shelf Storage, Block Storage, Etc.
Both variations support partial picking as well as multiorder picking.
Various types of picking are supported: Pick-by-Voice, Pick-by-Light, Pick-by-Vison, Etc.
Pick & Pack The system initiates a superordinate stock order, which contains the picking HUs for all the warehouse tasks that need to be created, which the warehouse worker needs to pick subsequently. The generated stock order will be shown in the activity area in addition to all the warehouse taks.
Catch Weight With Catch Weight Management, products in the warehouse can be stored with two independent and equal units of measure (piece and kilogram).
