SAP ALE (Application Link Enabling)
Distributed Applications
Business processes can be distributed using ALE. ALE is used to distribute data, master data and transaction data across different systems.
The ALE concept always relates to an enterprise structure with areas that have central tasks and areas with tasks that are decentralized.
It may be practical for organizations to use separate application systems so that application components can be installed and operated on decentralized systems that are technically independent of each other.
The ALE concept supports the implementation and operation of distributed SAP applications. It is based on business-controlled messaging with consistent data storage on loosely coupled systems. The applications are integrated through the message exchange, not via a central database.
To implement a distributed, yet integrated system, the customer must specify in a logical model, which applications are to run on which systems and how the applications are to exchange data with each other.
On the technical side, the data exchange is carried out via IDocs (intermediate documents) as used in the EDI (Electronic Data Interchange) interface. On the application side, EDI supports information exchange between R/3 systems in different enterprises, whereas ALE supports information exchange within one enterprise. The ALE distribution mechanism is similar to the EDI mechanism. In ALE, business processes are distributed at the transaction level.
