Hi Everyone, I am creating a customer refund in case of refund process , and add the payment option from sales order and getting this error "Gateway Response Code: 422 > validation, 167: Original pspReference required for this operation". but in customer refund there is no any field available for adding P/N reference field. can anyone help me out. Thanks in advance.

It sounds like there's a script acting on this record. Are you creating the refund in UI or in code? If it's not a User Event that creates the record, I'd check the logs of User Events and Workflows that operate on the record - it may be that something is deployed to the record that shouldn't be, or there is a bundle that you need to update.

This has something to do with credit card processing - who are you using to process credit cards in NS?
