How can we unpack or unpick an item fulfillment on a canceled sales order?

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that NetSuite does not provide a direct way to cancel or undo an Item Fulfillment without deleting it. The proper process would be to only fulfill once the warehouse has confirmed that they can fulfill it. Technically no fulfillment should be made until it is physically picked. If you are trying to cancel a sales order that has no linked item fulfillments, you might encounter an error. This could be due to a variety of reasons, such as the presence of a customer deposit. In such cases, you can try to close out each line item on the sales order. Make sure all the line items have quantity and then click "close" on the line items. Doing this will close the Sales Order. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
