Decentralized Warehouse Management (LE-IDW)

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:

interactsmoothly

be flexible enough to adapt to changes

perform their tasks cost-effectively and quickly

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).
