Hi Roopa,
This we can achieve..
just go through this steps...
step 1 : create one bsp component with the same name what you have deleted previously in se80.
example : i have already deleted bt11h_oppt compnent. so now again i have created bt11h_oppt component in se80 save check activate.
step 2 : again right click on that component go to other functions->version management.
you can see the standard component version over there.
the first button is compare button that will compare your component and there is same component which is existed in quality.
step 3 : click on retrieve that will be available in your system..
try this nd let me know if have any queries.
Thanks & Regards,
Srinivas.
