Hi Ankita,
Go to transaction POWL_COCKPIT and look for the corresponding application ID.
1) Within a application ID there will be n number of queries registered. You have the choice to delete the individual queries.
2) If you don't want to see the entire range of queries within that app ID, you can delete all of those.
Attached are some screen shots from POWL_COCKPIT
Regards,
Ravi
