CyberSource integration

We went through the oracle documentation regarding this and completed all the setups needed in both CyberSource and Fusion. Now we are able to create credit cards at customer and bill management portal in CyberSource Hosted page and also completed the transaction flow successfully.

Please shed some light on the below queries

1. We have been creating new Credit card at customer master with the dummy credit card details in Testing Guide (cybersource.com) provided by CyberSource and card got successfully saved in customer master. Then created the invoice with Credit card receipt method at invoice level, later we ran ‘Create automatic receipts’ program for sending authorization to CyberSource. However, sometimes we are getting the Authorization status as “Succeeded” and sometimes as “Failed” with the reason code 203 {Decline. General decline of the card. No other information provided by the issuing bank} even though with the same card which got authorization as successful.
