SAP EWM: Key Functions and Benefits (Reference Guide)

Most SAP EWM reference guides are a feature list you skim once and forget. This one is different: follow the real physical flow through a warehouse below, then go as deep as your project needs — six dedicated series cover the mechanics most references only mention in passing.

The Full Picture: Inside an SAP EWM Warehouse

Every function described below happens somewhere on this floor. Follow the physical path from the inbound dock through goods receipt and QC, into reserve racking, down to the pick face via replenishment, out through packing and wrapping to the outbound doors — plus the automated MFS zone. Each numbered step shows the real transaction behind the move.

Key Functions of EWM

1. Inventory management at bin level
2. Bin determination on goods receipt
3. Stock movement on goods issue
4. Stock transfer
5. Physical inventory, kept in sync with ERP
6. Inbound and outbound deliveries are distributed, and technically EWM works as a decentralized warehouse even when embedded in SAP.
7. The Warehouse Management Monitor is a powerful tool that lets you:
   • Supervise and manage warehouse documents and processes
   • Check stock at bin level
   • Verify workload
   • Monitor material flow in an automated MFS system

Every one of these functions is governed by a single configuration object — the Warehouse Process Type — which decides how each task actually behaves, down to which storage type search sequence and confirmation profile it follows. We cover the full mechanics in our WPT series.

Business Benefits of SAP EWM

Automation & RF

1. EWM integrates with automation technologies such as:
2. RF,
3. RFID
4. Pick-by-Voice
5. Interface to external system (warehouse control unit)

EWM supports RF integration across a wide variety of RF devices, through three supported environments:

• GUI-based
• Character-based, connected via SAP Console
• Browser-based, connected via ITSmobile

Quality, Analytics & Reporting

• Quality management that controls product movements within the warehouse based on quality inspection criteria — you can also use QIE («Quality Inspection Engine») to map QM processes.

• A very robust tool such as the Warehouse Monitor, which supervisors can use to update and monitor activities and resources. Warehouse information is available online, and the monitor can be configured by the user without ABAP technical knowledge.

• For BI analysis, EWM includes:
• BI content
• BI content extensions
• BI content extractors

These analysis tools are used to measure and evaluate business improvements. You can obtain data such as executed workload, process exceptions, service measures, work orders, warehouse tasks, and workload volume analysis, among other metrics.

Labor & Resource Management

• Another EWM functionality used for managing warehouse resources is Labor Management (LM), which can integrate with SAP HR or external HR systems to facilitate productivity-based pay management in the warehouse. Resources can be evaluated by comparing standard results against operational results. It supports analytical functions available in BI content.

LM provides information for planning and tracking productivity, and also serves as a tool to assign tasks to users in an optimized way — that is, to correctly distribute tasks across the resources available in the warehouse.

LM is especially useful in warehouses that rely heavily on manual processes and where complex tasks are performed daily.

• Resource Management (RM) manages warehouse resources, and this functionality helps avoid manual task assignment to users — it is used in both RF and non-RF environments.

Logistics & Fulfillment

• Shipping and receiving can be implemented with or without Yard Management. It is used to manage inbound and outbound warehouse movements — within EWM you can create a series of elements to control each stage of products entering or leaving the warehouse, such as: control points at inbound/outbound doors, loading/unloading points, and assigning deliveries to transportation units.

Yard Management is also a component used with warehouse receiving and shipping processes, managing truck movements to register their entry and exit.

1. Wave Management — in EWM, deliveries can be grouped by user-defined rules using a wide variety of criteria, and these rules can be executed automatically. A «Shipping Cockpit» functionality lets you visualize and plan deliveries and transports on a single screen.

• EWM offers advanced integration for procurement and receipt of products from production, as well as integration with inspection processes to evaluate production samples.

Storage & Automation

• EWM includes a Value-Added Services («VAS») functionality — additional services can be performed on products received or shipped from the warehouse, adding value to the product, such as labeling, building kits, or packing multiple products at work centers, where auxiliary materials can be consumed. VAS is one of the key differentiators that adds value to EWM.

• EWM has a process called «Slotting and Rearrangement» (storage planning), used to plan and execute optimized product storage tasks based on product characteristics and warehouse movements — this optimization is designed to make picking processes more efficient.

• Material Flow System (MFS) enables the configuration and connection of an automated warehouse to EWM. MFS connects to PLCs to retrieve information from warehouse processes. A «warehouse control unit» is not required — telegrams are used instead.
