Defining Logical System Names for Clients (SAP Library

Defining Logical System Names for Clients

To avoid any confusion, participating systems in a distributed environment must have an unique ID. The name of the logical system is used as the unique ID. This name is assigned explicitly to one client in an R/3 System.

When you have set up two clients for the exercise, you must notify them which logical systems exist in the distribution environment and what the description of their own client is. You can find the functions required for this in the R/3 Implementation Guide under Basis ® Application Link Enabling (ALE) under Sending and Receiving Systems ® Logical Systems.

Example

Client 100 is named logical system LOGSYS0100.

Client 200 is named logical system LOGSYS0200.

To maintain the logical systems in the distribution environment (function Rename Logical System):

Execute the function and enter a logical system (LOG. SYSTEM) and a short text for each of your clients.

Save your settings.

If you are using two clients in different systems, make sure your settings are the same in both systems. When using two clients in one physical R/3 System, you only have to make the settings once, since the entries are client-independent.

Example

Log. System

Short text

LOGSYS0100

System A, client 100

LOGSYS0200

System B, client 200

Assign the respective logical system to both the clients. Choose Assign Logical System to Client.

Execute the function in both clients.
To display the client maintenance screen, double-click on a client.
In the Logical system field, enter the logical system to be assigned to the individual client.
Save your entry.
