AP Invoices for an Operating Unit that are not Subject to the OU's Tax Configuration

In R12 Payables, I have a Swiss operating unit where Swiss VAT tax codes have been set up in the EB Tax module. When an AP invoice is manually entered into this Swiss OU, tax distributions (recoverable & non-recoverable) are created for each invoice line even when no VAT tax code is applied to the invoice.  However, in such cases, these tax distributions have zero values, so my users tolerate these undesired tax distributions.

I attribute this to the tax configuration in our EB Tax module where this Swiss OU is linked to a "tax".


But now I want to start importing AP invoices into this Swiss OU where the invoices would have no tax AND we do not want any zero-valued tax distributions created.
