Is it possible to have two different tax details reference lines (referencing the same item line) with the same tax code? I'm getting an error related to this "Tax Details already contain the Tax Code value that you chose for the selected Tax Details Reference." but we are getting multiple District tax results back for the same item from our tax service provider. E.g. we have three different "DISTRICT" tax detail lines that all have their own rate.

TR would allow as many details as you wanted to configure. What configuration options does your provider have?

I guess that's what I'm trying to figure out; is there some sort of configuration setting I can configure to enable multiple tax detail lines with the same tax code? Neither SuiteAnswers or Vertex Community seems to be particularly helpful on this point.

It doesn't seem you can do it in the UI. Can you combine them into a single district line?

yes, can programmatically in theory, but what a PITA versus just adding in a separate line, especially when you factor in the fact that you'd have to prorate the tax basis it starts getting somewhat complicated.

For sure. We just finished a migration to SuiteTax and handled something similar on the 3rd party side before the data was sent back to NetSuite.

it's also possible that I'm using tax code for the completely wrong thing. I don't think so, but maybe 🤷‍♂️

In our TR code we allowed clients to have inputs from multiple zones but if they were mapped to same tax code it would aggregate. Otherwise you would tell the provider engine what conditions to parse out to other unique codes
