If you miss submitting your ITR-V within 120 days, your e-filing will be considered as null and void; it means that it will be considered that you have not yet filed your return. In such a case you will have to file revised return, get a new ITR-V and submit the same within 120 days.

thanks for your reply

but when i am going to validate revised ITR an error is generated i.e. 'receipt no.'

In the Receipt No. column fill the original return E-filing acknowledgement no. with date in the respective column.
