Why is the sales order unlinked from the invoice?

AI generated answer (using internal Slack threads):

The sales order can become unlinked from the invoice in a few scenarios. One common scenario is when all the sales invoice lines are deleted and then re-added. This action breaks the link between the order and the invoice. Another scenario is when the form is switched to a cash sale. This action unlinks the deposit, which in turn can unlink the sales order from the invoice. It's also important to note that NetSuite considers a payment to a Sales Order to be a Customer Deposit. Therefore, if you want to link Payments to a Sales Order, the Invoice record is the join. Sales Orders have no General Ledger (GL) impact and the Invoice is the one with the GL impact that the Customer Payment record needs to go against, not the Sales Order. Please note that these are general scenarios and the exact reason may vary based on the specific configurations and workflows in your NetSuite environment. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
