Hi Kalpana,
Please check the related entry in transaction SICF.
To search the BSP pages go in below level "/default_host/sap/bc/bsp".
If this not work, try to in the SE80 and delete the class enhacement, and go to the sm34 transaction and put the "BSPWDVC_CMP_EXT" view, find your enhancement set and then delete the component from the enhancement definition.
Regards
Anderson
