Hello aspirant

After the JEE Advanced exam, when the results are announced the process of counselling starts. You have to register for counselling if you want to take admission through JOSSA. When you are allotted a college, you have to go to reporting center. At the reporting center you have to show your caste certificate in order to get admission through your category rank and percentile. If you fail to show the category certificate then, you will get admission through your CRL and no category rank or percentile is used.

Hope this helps.
