How to create sales order with sales tax on header level with csv?

AI generated answer (using internal Slack threads):

To create a sales order with sales tax on the header level using CSV, you would need to follow these steps: 1. Prepare your CSV file with the necessary columns. The columns should include the sales order details and the tax code/tax rate for the sales order. The tax code/tax rate should be the same for all lines if you want to apply it at the header level. 2. In NetSuite, navigate to Setup > Import/Export > Import CSV Records. 3. Select the record type as 'Sales Order'. 4. Choose the CSV file you prepared and map the columns in your CSV to the fields in NetSuite. Make sure to map the tax code/tax rate column to the 'Tax Item' field. 5. Run the import. NetSuite will create sales orders based on the data in your CSV file, with the tax applied at the header level. Please note that if you want to update the tax code/tax rate for multiple lines on an existing sales order, you can also do this via CSV import. You would need to include the line number or line sequence number in your CSV file, and then map this to the 'Line' field during the import. Remember, if you change the shipping address and then change it back, the tax will recalculate. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
