can you create a return authorization against unbilled lines on a sales order

AI generated answer (using internal Slack threads):

In NetSuite, the "Authorize Return" button typically appears after an Invoice has been created from a Sales Order. However, if you need to create a return authorization against unbilled lines on a Sales Order, you may need to use a workaround or custom scripting. One possible workaround is to create a new return authorization form, approve the return, ship the return to your vendor, and then enter the corresponding credit or refund for the return from your vendor. This process should allow you to create a return authorization against unbilled lines on a Sales Order. If you're comfortable with SuiteScript, you could also write a script to render a button and manually transform the Sales Order. This would allow you to bypass the built-in functionality and create a return authorization against unbilled lines on a Sales Order.
