Could anyone help me to resolve to the below exception that we get when we try to update the TaxDetails in an existing invoice?
&gt; Tax Details already contain the Tax Code value that you chose for the selected Tax Details Reference

netsuite thinks your tax code is a duplicate

you probably need to check the request to make sure it isnt

Thanks <@U5TF1GQ20> for your response. I was trying to understand why NetSuite thinks it as a duplicate though I send only one taxDetailLine.

I figured out the cause, NetSuite appends the taxDetails lines that I send to the existing lines. After setting the flag replaceAll to true, it worked.
