Link betweeen BW and R/3

Question

Hi All,
I want to know the steps to create a connection between the R/3 and BW. Below are the steps which I know and I am not sure how far are they correct. Could someone please have a lokk at them and let me know if they are correct. The steps below are from BW side. Do we need to do the same in r/3 side also?
1. Create RFC destination using SM59 for all the Bw clients and R/3 Clients.
2. Create Logical Systems in SPRO for all the BW and R/3 clients.
3. Creat clients and assign the logical systems to them in SCC4.
4. Creat source systems in BW using RSA1 and going to source systems.
Are these the only steps in BW? Are these in correct sequence? Do we need to do something using SU01?
Please help me in this. All the helpful answers will be highly rewarded.
Thanks,
RPK.

Hello
I am not aware about the automatic creation. Arun ! could u elobrate ?
check this,
***From a doc,
2.1     SAP R/3

Use
This activity allows you to change Customizing settings.
Prerequisites
You have logged on to the system in English in order to start with the installation of the Best Practices Scenario.
Procedure
Run the following activity:
SAP R/3 Role Menu     : Define Client Administration (SAP R/3)
Transaction Code     : SCC4
SAP R/3 Menu     : Tools -> Administration -> Administration -> Client Administration -> Client Maintenance
Then carry out the following steps:
1.     Choose Display -> Change.
2.     Confirm the warning message Caution: The table is cross client.
3.     Select your SAP R/3 client and choose Details.

•     eCATT and CATT allowed.
5.     Save.
6.     Go back to the SAP Easy Access menu.
2.1.2     Defining a Logical System for SAP R/3 (SAP R/3)
Use
The purpose of this activity is to create a logical system for your SAP R/3 System. To enable communication between systems within your system landscape, you must
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
Carry out the following steps:
1.     Access the transaction using:
SAP R/3 Role Menu     : Defining a Logical System for SAP R/3 (SAP R/3)
Transaction Code     : SPRO
SAP R/3
IMG Menu           : Basis Components (for R/3 Enterprisse: 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.
Log. System                                    Name
<Logical system 2>, for example DS7CLNT723 SAP R/3 System
To designate logical systems, apply the naming convention
Users
2.     In the User field, enter RFCUSER.
3.     Choose Create.
4.     On the Maintain User screen, enter the following data on the Tab entry screens:
Address     
Last Name     
Function     
Logon data
User type     System
Password     LOGIN
Profile
Profiles     SAP_ALL
            SAP_NEW
            S_BI-WX_RFC
Defaults
Logon Language     EN
5.     Save your entries.
Got this on SDN post, check with these.
