Go to Sales Return > New Sales Return, pick the party, and add the items and quantities being returned.
A sales return is its own document with its own serial number — it doesn't modify the original sale. If the return qualifies for e-invoicing (you're above the e-invoice turnover threshold), generate the IRN for it the same way you would for a sale, since a sales return is a credit note you're issuing.
If goods are physically moving back to you above the e-way bill value threshold, fill in the transport details so you can generate an e-way bill for the return shipment too.
