3.1 Defining Sending and Receiving Systems

The sending and receiving systems must be defined for messaging. In order to distribute data between systems you must first define both the sending and receiving systems as unique logical systems.

For this particular solution, we recommend defining two logical systems. One logical system represents the driver and acts as the receiver system. The other logical system represents the SAP system and acts as the sender system. Because only one of these clients is used as a data source (that is, the client/logical system where SAP User data is stored and “actions” occur), there is no need to assign a client to the receiving logical system.

NOTE:Depending on your current SAP environment, you might not need to create a logical system. You might only need to modify an existing Distribution Model by adding the USERCLONE message type to a previously configured Model View. For more information, see Creating a Distribution Model.

It is important, however, that you follow SAP’s recommendations for logical systems and configuring your ALE network. The following instructions assume that you are creating new logical systems and a new model view.

3.1.1 Creating a Logical System

  1. In SAP, type transaction code BD54.

  2. Click New Entries.

  3. Type an easily identifiable name to represent the SAP sender system. SAP recommends the following format for logical systems representing R/3 clients: systemIDCLNTclient number (such as ADMCLNT100).

  4. Type a description for the logical system (such as Central System for SAP User Distribution).

  5. Add a second logical system name to represent the Identity Manager external receiver system (such as DRVCLNT100).

  6. Type a description for the logical system (such as Identity Manager User Management Integration).

  7. Save your entries.

3.1.2 Assigning a Client to the Logical System

  1. In SAP, type transaction code SCC4.

  2. Click Table View > Display > Change to switch from display to change mode.

  3. Select the client from which you want User information distributed (such as 100).

  4. Click Goto > Details > Client Details.

  5. In the Logical System field, browse to the sender logical system you want to assign to this client (such as ADMCLNT100).

  6. Save your entry.
