Is form 15ca /15cb required for refund due to cancellation of export order

If the transactions are covered under Rule 37BB, then neither of 15CA nor 15CB are required.

Yes, Form 15CB is required if the total remittance exceeds ₹5 lakh in a financial year and TDS is applicable. A single Form 15CB can be issued for multiple invoices to the same party, provided the nature of the payment is the same. However, it's best to confirm with your CA or bank, as some may prefer separate forms for each remittance.
