What happens when a NAV option is off?

With Validate Hungarian tax numbers via NAV off, Hungarian partners get no NAV check and no auto-fill from NAV: the lookup says NAV validation is not enabled, and you enter the details by hand. Lookups for other countries (VIES, ANAF etc.) are not affected by the NAV options.

Option by option:

• Validate Hungarian tax numbers via NAV – off: looking up a Hungarian tax number runs no NAV check, and auto-fill does not work either, because it builds on this. The weekly automatic partner check then validates Hungarian partners through the EU VIES system.
• Auto-fill company data from NAV – off: tax number validation still works (if on), but name, address and sites have to be entered by hand.
• Synchronize invoices from NAV – off: new invoices reported to NAV are not brought into Demona. Invoices already imported stay.
• Reconcile existing invoices with NAV data – off: existing invoices are not compared with NAV's data, and re-fetching line items or the invoice chain does not work. Line items of new invoices arriving through sync are still downloaded.

If the team has no NAV credentials, all four features behave as switched off, whatever the checkboxes say.

Other countries (for example Romania, the Czech Republic, Poland and the other EU member states) use their own registers and are entirely independent of the NAV options. Looking up your own company details does not depend on them either.
