Hi Sreedhar,
Assuming you've extracted CR SP7's installation files to a folder on your local drive, browse to
<drive:>\<extracted folder>\Collaterals\Add-Ons\SAP\Transports
This is where you can find the right Transports for SP7 that need to be loaded on the SAP System.
For more info on Transports, authorizations etc, please have your BASIS admin go through this wiki:
