The documents need to be uploaded after seat allocation and the seat allocation results for CCMT have been put on hold. Let's say if the document is put on hold as the final year results have been not declared yet, then it might be valid or if its for any other reason, you might have to reach out to the helpdesk. Please reach out to the helpdesk at: ccmt2020help@mnit.ac.in (mailto:ccmt2020help@mnit.ac.in) mentioning the reason. They will be able to help you.
