Hi Mubashar,
Have you tried to find out this information at http://help.sap.com ?
It is a good practice to search before posting. Asking end-to-end and step-by-step/how-to guides is highly frowned upon here. If you simply search on google the same question you asked us, it is likely that you would have find the information you are asking for.
This SCN space SAP on SQL Server contains many documents, references, presentations and links to sources where you can find such information. The community exists basically to help people with particular issues when they are willing to do at least the basics (searching before posting is one of them) and exchange knowledge. There is also a SCN Wiki where you can find more information too about SAP on SQL Server:
SAP on SQL Server - SAP on SQL Server - SCN Wiki
I apologize if I have gone hard at any point, but I suggest you to do some reads before posting your questions here:
I would look at documentation in http://service.sap.com/instguides for more documentations and alsohttp://trainning.sap,com and http://open.sap.com if you are looking for a specific training.
Best Regards,
Luis Darui
