proper way of correcting and resending open invoices in case of amount mistakes

AI generated answer (using internal Slack threads):

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** To correct and resend open invoices in case of amount mistakes, you can follow these steps: 1. Create a Credit Memo: If the period is already closed, you can create a Credit Memo (CM) against the incorrect invoice. This will effectively cancel out the incorrect invoice. 2. Create a New Invoice: After creating the CM, you can then create a new standalone invoice for the correct amount. 3. Link the New Invoice to the Original Sales Order: If you need to link the new invoices to the original sales order, you can do so manually. However, please note that applying the credit memo might make it appear as if the order was fully billed. 4. Resend the Invoice: If you need to resend multiple invoices in bulk, you can create a workflow that resends them. You can do an update (perhaps to a custom field checkbox to resend) to each invoice you want to resend. You can use a Saved Search as the input search for the workflow. The workflow will check the search for any Invoices that don't have a message and will attach the PDFs to all the records when sending. Please note that this process might vary depending on your specific NetSuite setup and business processes.
