Hello Sudhakar,
You can maintain resolution categories in Administrator > Service and Social Settings > Service Categories.
Add a new Service Category Catalog. In Catalog Structure tab you can add lines and select category type "Activity".
I've never configured all of these functionalities but I think that everything is determined by the structure you created. In the screen, one field may filter the others.
In admin guide, page 469, you can find something about it.
Regards,
Alexandre.
