How to import an itemized received invoice from another software with correct VAT-inclusive totals when rounding differs?

It is necessary to first import the invoice header without prices and without line items.

In the second step, we import the invoice line items, after which the rounding item will automatically be imported as well, according to the rounding setting configured on the issued invoice document type.

See examples in the attachments:
