how can i override a tax rate on line leve of the order via suitescript?

AI generated answer (using internal Slack threads):

To override a tax rate on the line level of an order via SuiteScript, you would need to change the tax code associated with that line. However, it's important to note that you cannot directly edit or override the tax rate field in the Sales Order line by script. If you're using Avalara/Avatax, you might encounter difficulties setting the tax fields via server-side SuiteScript. In this case, you can try setting the

custbody_ava_taxoverride

or

custbody_ava_suspendtaxcall

fields. If you're still having trouble, you could try setting

taxamountoverride

to null in a user event script that runs after Avalara's script. This would disable the mechanism that Avalara uses to disable NetSuite's native tax features. If you're using the US tax engine, there is a Tax Override checkbox that prevents NetSuite from recalculating the tax. However, it's not clear if this can be set via SuiteScript. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
