Purpose

This component describes the SAP Warehouse Management System (WMS) as a decentralized stand-alone system that is operated separately from a centrally operated ERP (Enterprise Resource Planning) system.

To achieve a high level of efficiency in the supply chain, all system components involved must:

The warehouse, which is used not only for the storage of goods but also particularly for the distribution of goods, represents the link between internal and external logistics. Since warehouse processes constitute an essential integral part of the supply chain, the SAP WMS is integrated with the entire logistics process. In addition, in order to achieve the flexibility required, the SAP WMS is able to carry out these warehouse processes independently.

Implementation Considerations

Especially in warehouses characterized by high throughput, the Warehouse Management System must always ensure quick response times. If the Warehouse Management System runs on the same machine as the ERP system, update problems may arise. An additional requirement is that the WMS must be available 24 hours a day - regardless of whether other systems are available or not. This 24-hour availability must be combined with low downtime risk to ensure that it is possible for the WMS to perform all logistics processes which are often closely integrated.

Not only the SAP R/3 WM System but also third-party systems must be able to interact smoothly with the SAP system.

For a complete description on how to configure your system for using the decentralized WMS, refer to the documentation of the Implementation Guide (IMG) under Logistics Execution ® Decentralized WMS integration.

Integration

You can interface the Warehouse Management System as a stand-alone component with the SAP system or integrate the SAP Warehouse Management System with any ERP system you prefer. In both cases, the ERP system and the Warehouse Management System can run on separate machines.

A warehouse that is managed with decentralized WM under the SAP R/3 system always communicates with exactly one ERP system.

In the decentralized WMS, there is no integration with a Transportation Management System (TMS).

Features

This graphic is explained in the accompanying text

In the first step, the Warehouse Management System has been implemented for the "distribution center" scenario. This scenario describes a warehouse that is primarily used for the distribution of goods and is not linked to a production plant. All business processes, including quantity-based inventory management, are carried out in the ERP system whereas the decentralized WMS is responsible for the necessary processes for goods receipt, warehousing, and distribution.

As a result, this new functionality is split up into two areas:

Application Area

You can use the warehouse as a stand-alone component if you plan to implement distribution center control on a separate decentralized machine that is not linked to the business application. You can use the SAP system to operate only one or both of these systems.

Deliveries are always created in the central ERP system.
