How to update tax code on transaction via csv import

AI generated answer (using internal Slack threads):

To update the tax code on a transaction via CSV import, you can follow these steps: 1. Create a saved search that includes the line number or line sequence number of the sales order lines you want to update. This will help you identify the specific lines you want to update in your CSV file. 2. Prepare your CSV file with the necessary updates. The CSV file should include columns for the internal ID of the sales order, the line number or line sequence number, and the new tax code. 3. Go to Setup > Import/Export > Import CSV Records. 4. Select 'Update' as the import type and 'Transactions' as the record type. 5. Map the columns in your CSV file to the corresponding fields in NetSuite. The internal ID should be mapped to the 'Internal ID' field, the line number or line sequence number should be mapped to the 'Line' field, and the new tax code should be mapped to the 'Tax Code' field. 6. Click 'Next' and then 'Finish' to start the import process. Please note that this process will only work if you are using the legacy tax system in NetSuite. If you are using SuiteTax or an external tax solution like AvaTax, you may not be able to update tax codes via CSV import. In that case, you may need to use a different method to update your tax codes. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
