The following registry keys can be used for the configuration of invoices:
•Original invoice for follow-on services
Enable registry key [41457] to be able to print the number of the invoice in which the follow-on service was included originally. In addition, enable [41459] to also include the text “Original invoice:” .
This key is, for example, required for the “stayover tax” in Greece, which is shown in a separate invoice and must show the invoice number that orginally produced the tax.
•Follow-on services with amount 0,00:
Enable registry key [33947] to avoid the posting of follow-on services with an amount of 0,00.
