Kaliappan - take a look at DriveWorks. You will enter all of the data needed for a project once. The next time you are doing a similar project you will only have to enter the data that is different and DriveWorks will automatically generate new drawing, lists, etc. A copy of DriveWorks Express comes with every seat of SolidWorks and can be found under "Tools".
