Hi Madhuraji,
Please be informed that under normal or general circumstances once a report has been generated the details of that report or rather the credentials of that report generated cannot be edited any further but that most likely differs from one place to the other.
Now to answer your question, what I suggest you to do is first check to see if there is any scope of correction wherein you can change the paper code and get the report printed once again and if that is not the case then you should address this matter to the college authorities thorough post or in person via a letter which should mention your credentials accurately and request them to rectify the error and generate you a new report.
BEST WISHES!
