# Common Issues Faced

#### Q-> Facing Error in  canceling IRN, (if EWB  created with the same IRN)

* Please Cancel the EWB with the given IRN first and then try to cancel the IRN

#### Q-> Facing Issue in  generating IRN with same invoice no  of an already cancelled E-invoice.

* Currently, It is not possible to generate IRN again with the same invoice no, because IRN is already generated for the same in NIC (govts)  database. It is a limitation from govt and not Cleartax.

  To resolve this you have to upload the invoice again with a diff invoice number and generate IRN again.
