# I’m unable to push an invoice to IRP because it indicates that the IRN has already been generated and cancelled. How do I resolve this issue?

Let’s say you created an invoice INV-001, and it was successfully pushed to IRP. Later, you cancelled this invoice either in the IRP portal. Subsequently, you deleted this invoice from Zoho Books. If you attempt to recreate an invoice with the same number (INV-001) in Zoho Books, you will encounter this error. To resolve this issue, you will need to use a different invoice number.
