Hi Chinna,
Below are the steps to be followed for the SS creation in BW :
Prerequisites :
1.System Number
2.System IP address
3.ALEOLTP like userid and password – this is the RFC user ID in the R/3 system. Usually set to communication - must be set to dialog in the R/3 Source System for the duration of the create/restore connection process.  Note: the password must be in capital letters.(If all instances are in unicode system)
1.At the time of making the connection, the R/3 source system will need to be opened for client independent configuration.
2.If it is a connection create or restore, the personal userid of the person doing the work must have SM59 access.
Follow the naming convention which is being used in your system.
1.     Logon to r/3 source system using the r/3 RFC userid to check that the userid has been set to dialog user. It is mandatory that the r/3 source system userid be setup temporarily as dialog to create the connection. If not contact the requester to have this done before continuing with the next step.
Note: When re-checking to ensure that the r/3 userid is a dialog user, you may get prompted for new password. Change password, and make a note of the new password. Use this new password in the steps that follow for the r/3 RFC userid.
2.     Logon to BW system using your own userid.
3.     Enter transaction RSA1, In Source Systems, right-click on Source Systems as shown below to create new connection.
4.     In the screen select the appropriate Source System connection type. Suppose your  are creating connection for r/3 instance, so in this case we pick the very first option.
5.     A popup window will get displayed asking for the necessary information. To fill in the appropriate information in the that screen you need the following information concerning the r/3 source system.
•     IP address (Application Server) &
•     System Number
Get this information for the r/3 source system from the SAP Logon Pad.
6.     If Parameters have been incorrectly entered  then  the following error message will appear : “Check connection parameters for the source system”.
7.     Re-check and re-enter correctly. If all is good then You will see the following prompt : Please log on as an administrator in the following screen.”Click green check to continue.
8.     This will bring you to the r/3 logon screen. Logon using the r/3 RFC id. Once logged on click Check in ‘Check RFC destination’ dialog box.
9. Consider the r/3 RFC destination screen.
10. Check to make sure that BW system information (Userid, IP address, System Number etc) is correctly showing in the Technical Settings and Logon/Security tabs. Next do the following,
     Step 1: Enter password for the BW RFC userid id.
     Step 2: Save Settings
     Step 3: From Test Menu , click on authorization. Ensure there are no errors
     Step 4: Back out of screen.
11.     System may ask you to logon as administrator again. Logon as in Step 10. This time click on Use in ‘Check RFC destination’ dialog box.
Connection related processing will start up at this time, and continue for a little while (can be a couple minutes or more).
12.     Subsequently, a dialog box will show up on the screen.
13. Pick option, Replicate As Well.
Replication and activation of data sources & transfer structures will begin.
With the completion of this step you will have successfully established this source system connection. To confirm, right-click on the new source system entry and click on check
14. If the connection is good, the following message with the source system ID will display at bottom left corner of screen : Source system connection is Ok”.
Hope this will be helpful to you.
