When trying to process a credit card from Billing tab on a sales order the only option for handling mode is "save only"

AI generated answer (using internal Slack threads):

In NetSuite, when processing a credit card from the Billing tab on a sales order, the only option for handling mode is "save only". This is by design and is related to the payment instruments feature. When this feature is enabled, the traditional "Charge Credit Card" checkbox is replaced with a field called "Handling Mode". If you need to retry a declined credit card transaction, you would typically edit the payment record and re-save it, which would re-trigger the merchant processing. However, with the payment instruments feature enabled, this process may be different. As for adding credit cards to a sales order without saving them to the customer account, this is possible. You would simply need to uncheck the "Set as Default" box when adding the card. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
