How to tell whether to use istaxable or taxcode in a sales order line item?

AI generated answer (using internal Slack threads):

Based on the conversations, the decision to use

istaxable

or

taxcode

in a sales order line item depends on the tax accounting setup of your NetSuite account. If you are using Basic Tax Accounting, the

istaxable

field on the customer record and the item record is used to determine if tax should be applied. The

taxcode

field on the item record is used to determine the tax rate. If you are using Advanced Tax Accounting, the

taxcode

field on the sales order line item is used. This field is populated based on the tax settings of the customer and the item. The

istaxable

field is not used in this case. To set the tax code on a sales order line item based on the customer's tax item, you need to ensure that the "Enable Tax Lookup on Sales Transactions" and "Per-Line Taxes on Transactions" settings are enabled. You can find these settings by navigating to Setup > Accounting > Set Up Taxes. If you need to update the tax code/tax rate for multiple lines on a sales order, you can do this through a CSV import. You will need to include the line number or line sequence number in your CSV file. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
