Why does JustOn not create booking details for cancellation invoices?
Under certain circumstances, the booking detail creation for cancellation invoices may fail. A possible reason may be that the original invoice was finalized without creating booking details – if, for example, you started using JustOn only to generate invoices, and later decided to create booking details as well.
Understand the way JustOn Billing & Invoice Management creates booking details for cancellation invoices:
Generally, it creates the booking details when finalizing an invoice based on the invoice data. For cancellation invoices, however, this is not the case: Instead, JustOn creates the new, "opposite" booking details based on the booking details of the original invoice, inverting the amount and adjusting the date.
For more details, see Bookkeeping Data for Cancellation Invoices.
Now if you cancel an invoice issued before you have enabled the booking detail creation, JustOn simply cannot create booking details for the cancellation because there are no original booking details.
Info
To produce booking data for the cancellation invoice, we recommend to use the same way you used for the original invoice data – via CSV export, manually or through your tax consultant using the PDF files, or some other way. There is a technical workaround, however, but be aware that booking details JustOn would create may differ from the original booking data – which will very likely cause conflicts in your accounting system.
