how to update the tax line on a customer invoice csv

AI generated answer (using internal Slack threads):

To update the tax line on a customer invoice via CSV, you need to follow these steps: 1. Prepare your CSV file with the necessary columns. The columns should include the internal ID of the invoice and the new tax code or tax rate you want to apply. 2. In NetSuite, navigate to Setup > Import/Export > Import CSV Records. 3. Select the record type as 'Transactions' and the import type as 'Update'. 4. Upload your CSV file and map the columns in your CSV file to the corresponding fields in NetSuite. Make sure to map the tax code or tax rate column to the 'Tax Item' field. 5. In the 'Default Value or Reference Type' configuration, specify whether you are using the name or internal ID of the tax item. 6. Run the import. Please note that the tax item value should be specified as a combination of the {taxtype}:{itemid}. This is how the values are displayed in the dropdown when editing a customer. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
