Defining a Logical System for SAP R/3 (SAP R/3)

1. Define the systems as logical systems.
2. Assign the logical system for the SAP R/3 System to a client.

This enables the systems to recognize the target system as an RFC destination. If the logical system has already been created, skip this activity.

Logical systems are defined cross-client.

Procedure
Execute Transaction Code : SPRO
SAP R/3 IMG Menu : Basis Components (for R/3 Enterprise: SAP Web Application Server) -> Application Link Enabling (ALE) -> Sending and Receiving Systems -> Logical systems -> Define Logical System
2. Choose New entries.
3. In the column Log System, enter a name for the logical system that you want to create.
4. In the column Name, enter a description of the logical system.

Example of logical system SND100 <SID><Client number>

 

To designate logical systems, apply the naming convention
<SID><Client number>

5. Save your entries.
A transport request for Workbench appears.
6. Select an existing request or create a new request, if necessary.
A transport request for Customizing appears.
7. Select an existing request or create a new request, if necessary.

Assigning Logical System to Client

Execute Transaction Code : SCC4
SAP R/3 Menu : Tools -> Administration -> Administration -> Client Administration -> Client Maintenance
2. Choose Display ® Change.

Creating an RFC User (SAP R/3)

To enable communication between the SAP R/3 back-end system and the SAP BI System, you have to create an RFC user in the SAP R/3 System.
The RFC user in the application client enables multiple RFC connections. Skip this activity if an RFC User has already been created.

BW RFC / ALE  Setup
In SAP BW, you should create a system (not a dialog) user called BWALE. BWALE should have the authorization profile (not Role)S_BI-WHM_RFC.
You can convert this profile to a role, if you want.

This profile will give user BWALE the access needed to extract from
an OLTP system. The profile also provides the access required for staging
steps to get the data into InfoCubes.

SAP R3 RFC/ALE Set Up
You must set up a user on each SAP system sending data to SAP BW. For this example we will use R3 system.
 
Create a system user called  BWR3ALE.
This user should have the authorization profile (not Role) S_BI-WX_RFC.

This profile will give user BWR3ALE the access needed to connect
and send data to the SAP BW system.

Set up RFC destinations using SM59. If you don’t know ask your Basis Admin to set this up for you.
