The purpose of this guide on implementing SAP ALE whitepaper is to provide you with a methodology on implementing SAP R/3’s ALE technology. For the executive who is looking into deploying ALE the first chapter will be of benefit as well as the summary for each of the remaining chapters which will give a good indication as to the level of effort that will be required in order to implement ALE.

It highlights the areas to look at; it gives example documentation and describes the implementation process in detail. It is not an idiot’s guide to implementing ALE. Detailed knowledge of the ALE functionality together with project management skills will ensure a smooth ALE implementation.

The Guide is divided into the following chapters:

1. Introduction to ALE. What is ALE? Why ALE?
2. ALE Assessment. Putting a project team together. Deliverables of the team. Setting standards. Investigation and position papers.
3. ALE Design. Design phase. Design document. Performance and technical implications.
4. ALE Configuration. Configuration & related procedures.
5. ALE Development. Describing ALE development. Development example.
6. ALE Operations Support and Production support procedures. Production support planning. Monitoring and archiving. Disaster recovery.
7. ALE general issues. ALE transaction codes, tables, programs… Glossary.

The Following Instructions walk you through how to set up an ALE Distribution scenario on one client, so that the same client serves as both the sender and the receiver system.

This kind of setup will help you to achieve a more economical testing environment and is also an elegant distribution technique for certain production environment scenarios, like to enable data distribution in cross-company business processes that are not supported by standard interfaces.

ALE (Application Link Enabling) supports the construction and operation of distributed applications. ALE handles the exchange of business messages across loosely coupled SAP applications, ensuring that data is consistent. Applications are integrated by using synchronous and asynchronous communication, rather than through a central database.

What is ALE?

ALE is SAP proprietary technology that enables communication of data between two or more SAP R/3 and/or R/3 and external systems.

ALE provides intelligent mechanisms which clients can achieve integration and distribution of applications and data. ALE technology facilitates rapid application prototyping and application interface development, thus reducing delays in implementation.

ALE comes with application distribution and integration scenarios, and a set of tools, programs, data definitions, and methods that you can easily configure to get an interface up and running.
