KB article 68794 indicates that presetting an InvoiceAmt with an AP invoice import is not necessary.
This is true. Tested with ABC data and no InvoiceAmt in the header record, which imported fine.

And the resulting invoice has an automatically calculated invoice amount. Perfect.

However, as soon as I change the invoice to taxable, it fails with an out of balance error, when using the exact same import (only changing TaxClass from NT to TX) and exact same data.


The vendor source files I'm dealing with do not have reliable tax calculations (constant penny rounding issues) and I need the import to work with taxes but without a pre-calculated invoice amount. Is this at all possible?
Yes, I know I can import the tax amounts as GL lines, but then I have to do a scripted manipulation of the import files to handle that, which I'd really like to avoid.
(My test system is v2018.5, if it matters).
