How to import an itemized received invoice from another software with correct totals including VAT, 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 a rounding item will automatically be imported as well, based on the rounding settings configured on the issued invoice document type.

See the example attachments below:
