Praneeth,
I just did the below steps:
On left navigation filter, search for Reports > View / Run
Click on All tab in the page that comes up
In the search bar, type in project. It should bring all the project related reports.
Now if you activate the Resource Management plugin, you should be able to see Resource Reports when you search for it in the left navigation filter.
Here are some links that you may find useful:
Project Reporting - ServiceNow Wiki
Resource Management reports
Project Financial reports
Portfolio reports
Hope this helps!
Thanks,
Neena
