How can i relate a sales order to an invoice during importing

AI generated answer (using internal Slack threads):

To relate a Sales Order (SO) to an Invoice during import, you can follow these steps: 1. Create a custom checkbox on the Sales Order called "Ready to Invoice". 2. Create a workflow that uses the Transform Record action to transform the SO into an Invoice. This workflow can be run on a schedule using the saved search criteria of "Ready to Invoice = T" or have it as an Event Based workflow so whenever the box is checked the invoice is automatically created on save. 3. Perform a CSV import to sales orders that checks your custom checkbox which would then trigger the workflow to create the Invoice. Alternatively, you can use the Billing Operations feature in NetSuite. This feature can use a saved search that's filtered for the checkbox "Ready to Invoice". Please note that when an invoice is created from a Sales Order, the "Created From" field on the invoice should automatically link back to the Sales Order. If you can't see this field, it might be hidden on your form. You can check this by going to the form customization settings. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
