Why is there a check number assigned to a customer refund created by a scheduled script when I set it to an empty string?

AI generated answer (using internal Slack threads):

The check number is automatically assigned by NetSuite when a customer refund is created, even if you set it to an empty string in your scheduled script. This is because NetSuite uses the check number as a unique identifier for each transaction. It's a system behavior that cannot be changed through scripting. If you don't want a check number to be assigned, you might consider using a different method for the refund, such as a direct deposit or a credit card refund, if these options are available and appropriate for your business process. Remember, if you're using a script to create the refund and you set the check number to an empty string, NetSuite will still auto-assign a check number once the transaction is saved. This is to ensure the uniqueness of each transaction and to prevent any potential conflicts or errors in the system. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
