hello, is it possible to override tax total in the Invoice record via a UE script? we have Avalara Integration, but its turned off to load legacy sales order and invoices. I am trying to set tax total in the invoice using a script, but I keep on getting the following error:

Is it possible to override tax total?

basic answer is no

I was able to override the tax total on Return Authorizations and Cash Refunds using this as @battk mentioned: currentRecord.setValue('taxamountoverride', taxTotal) In the case where I was using it, the tax we wanted to apply to these transactions was from our CRM and not NetSuite's built-in tax.

@battk I was able to override tax total using that field, but I am not sure if I understand this comment 😄 "keep in mind that if there was any chance of me having to use taxamountoverride I would answer no"

that field requires heavy scripting to make it work correctly

so I disabled Avalara in their configuration level. and then in the script, I still mark Tax Code as AvaTax per line, because they are basically calculated in Avalara from a different system. Then I set the taxamountoverride to the value I want and there seems to be no issue with that.

For existing transactions that have already charged tax, the Tax Override checkbox doesn't work as expected. Avalara "remembers" the tax and no matter what you do, it won't override the tax if you need to so you'll need to script it.

Thank you for the information @Eric B! however, the transaction that I am updating are legacy transactions that do not have Avalara called up on before.
