Hi,

Logical system is used to identify an individual client in a system, for ALE

communication between SAP systems. That's why you see a field for logical

system in the client master data in SCC4 (table T000). You use logical systems

in ALE config - this should be documented further in the IMG guide, or SALE and

BALE transactions.

Cheers.

Hi,

System in which applications run integrated on a shared data basis.

The distribution of data between systems requires that each system in the network has a unique identification. The logical system is used for this purpose.

In the SAP System the client corresponds to a logical system. You can assign a logical system to a client in the client maintenance (choose Goto -> Detail).

The logical system is relevant in the following SAP areas:

ALE general: two or more logical systems communicate with one another.

ALE - ALE business processes (for example, cost center accounting): definition of a system where a specific application runs. Changes to master data can only be made in this system, for example.

Workflow objects: the logical system in which the object is located is always included in an object's key.

When maintaining the logical system, note the following:

The logical system must be unique company-wide. It must not be used by any other system in the ALE integrated group. In a production system, the logical system must not be changed. If the logical system of a document reference is not set to initial and does not match your own, the system assumes the document is located in a different system.

A logical system is used to identify an individual client in a system, for ALE communication between SAP systems.

We define all communication in ALE as links between logical systems. A logical system is a system containing applications that are coordinated to work with one set of data. A logical system can be:

A specific client on a specific SAP system

A non-SAP system

A file-based interface

Since logical systems are the basis of all ALE configurations, the ability to define them should be restricted to as few people as possible

In the business service go to the menu Business Service --> Adapter Specific Identifiers and add the Logical System name

Creation of Logical system: TCODE : BD54

Logical system is a identifier to the system by which the system will communicate to the other system

you have a provision from sap to create the logical system

go to SM59 you can create the logcal system.
