Hi Praveen,
As far as I know there isn't any such process.
Also though this process might sound lengthy but maintain the consistency of your database and transport system.
May be this is the reason why SAP does not support MASS deletion.
You can try deleting entries from E070 and E070L but I will strongly suggest not to as when you can do it from SAP and OS level why touch DB directly.
