Arbeitsschritt in der Hartmetallverarbeitung



  • Since 1 July 2018, all data from invoices created for transactions between VAT-registered parties in Hungary (local outgoing invoices) must be reported to the Hungarian tax and customs office.
  • The data needs to be sent automatically to the tax authority in Hungary in an electronic, serially processed form (structural data), via the NAV (National Tax and Customs Administration of Hungary) interface.
  • This structural data is to be checked and processed in Orchestra using offsetting logic.
  • Due to the sensitive nature of the invoice data, this is to be stored in the Horn database in encrypted, tamper-proof form.
  • All changes to the data must be logged to ensure that the data is kept transparent and can be audited at any time.
  • With regard to version security, Orchestra must ensure that the current and correct versions of both systems (SAP system and NAV interface) are always used.



  • Integrate an SAP system with the NAV interface of the local tax authority.
  • Orchestra acts as its own SAP system and transfers electronically created invoices to the Orchestra database.
  • The invoice processing status at the local tax authority is automatically transferred back to the initial system in a separate process.
  • A technical check is performed.
  • The transaction remains open until a result (success or error) can be reported back to SAP.
  • The data is stored in encrypted form.
