The SAP Warehouse Management system (WMS) provides flexible, automated support in processing all goods movements and in managing stocks in your warehouse complex. The system supports scheduled and efficient processing of all logistics processes within your warehouse.

Implementation Considerations

If you manage your warehouse stocks with SAP Inventory Management (MM-IM), you manage the quantities and values of stocks in several storage locations.

In comparison, the WMS allows you to map your entire warehouse complex in detail to storage bin level. Not only do you gain an overview of the entire quantity of a material in the warehouse; you can also always determine exactly where a certain material currently is in your warehouse complex. With the WMS you can optimize the use of all of your storage bins and warehouse movements, and store material stocks from several plants together in warehouses with random storage.


The WMS is fully integrated into the SAP environment. Business processes, which you trigger in other application components, lead to physical goods movements in your warehouse. You organize, control, and monitor these goods movements with the WMS.

Storage Bin Management

You map your entire storage facilities in the Warehouse Management system. In doing so, you can set up various storage facilities such as automatic warehouse, high rack storage areas, bulk storage or fixed storage bins in various storage types, according to your needs.

You manage material stocks at storage bin level. You can define these storage bins according to your own requirements. Every storage bin in your warehouse is mapped in the system. This lets you monitor all warehouse movements at all times. You can follow where a certain material is in your warehouse.

SAP Inventory Management and the SAP Warehouse Management system are fully integrated. With its inventory procedure and recording of stock differences, the system ensures that the inventory balance in Inventory Management always corresponds to the warehouse stock in the WMS.

Goods Movements

You process all goods movements that affect your warehouse via the WMS. This includes goods receipts, goods issues, stock transfers, material staging for production, automatic replenishment, managing hazardous materials, and processing stock differences in your warehouse.

The WMS optimizes warehouse capacities and material flows using putaway and stock removal strategies, which you can adjust to suit your individual needs, or by using storage units.

Planning and Monitoring

The WMS offers you an overview of all goods issues and warehouse stocks. The system supports you in planning, monitoring, and optimizing work processes. For example, it gives you a foresighted view of the workload in the coming days or allows you to intervene in good time during critical warehouse processes, so that you can execute warehouse movements on time. Via the RF monitor, you get an up-to-date picture of all of the activities in the warehouse, which means that you can control the actual work in the warehouse using the RF monitor.

Radio Frequency Connection

In order to structure the work in the warehouse efficiently and cost-effectively, you control the warehouse workers’ work steps clearly and simply via mobile radio-frequency terminals.

Radio frequency connection (RF connection) to mobile date entry achieves quick and flawless data transfer. The RF machines receive data directly from the SAP system and transfer data back to the system. Using barcodes, you can record information to be recorded and verify it. This means that you ensure a high standard of quality in your warehouse.

Decentralized WMS

You can run the WMS as a standalone decentralized warehouse management system, independent of a central enterprise resource planning system (ERP system). For more information, see Structure linkDecentralized Warehouse Management.

Warehouse Control

WMS also has an interface to external systems (warehouse control units), so that you can integrate automatic putaway, stock removal systems or fork lift control systems into the warehouse management system for all warehouse movements with the help of this ALE interface.
