Hi Peeyush,
In order to review what features were added in the various 10.0 Support Packs since SP01 you need to review the Release Information Notes (RIN) on SAP Service Marketplace for each 10.0 Support Pack.
For information on performing the upgrade from 10.0 SP01 to the latest 10.0 Support Pack you should use the Sourcing/CLM Upgrade Guide (for either Oracle or DB2 - depending on your installation) which can also be found on SAP Service Markeplace.
Regards,
Ed
