You may want to verify the date of the ORIGINAL TRANSACTION. Cybersource allows you to perform a referenced refund (Cybersource refers to these as"follow-on credits", which references a prior transaction in the CyberSource system) within60 days of the original authorization.
If the original payment exceeds the 60 day threshold, you can no longer perform an electronic refund in Zuora. You will need to perform a stand alone refund in your Cybersource business center. After performing the refund in Cybersource business center you would need to perform an"external" refundin Zuora so that the information matches Cybersource.
