why "return authorisation" button is missing in sales orders?

AI generated answer (using internal Slack threads):

The "Return Authorization" button in a Sales Order in NetSuite typically appears after an Invoice has been created from the Sales Order. This is because the Return Authorization is designed to handle returns for items that have been invoiced and shipped to the customer. If the Sales Order has not been billed yet, the system does not consider there to be anything to return, hence the "Return Authorization" button does not appear. If you need to handle returns for unbilled Sales Orders, you may need to consider a different approach or customization, such as scripting to render a custom button and manually transform the Sales Order. However, please note that this would be a deviation from the standard NetSuite process and should be carefully considered and tested. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
