Further processing of document &1 &2 not possible (Faulty status)

What causes this issue?

You want to process a provisional invoice document using the method
<ZK>Change</>, <ZK>PreliminaryPostSingle</> or <ZK>DeleteSingle</>.
However, the system has encountered a status that does not allow further
processing.
This can be due to one of the following reasons:
With all the aforementioned methods, it is only possible to process
provisional invoice documents that have the status 'on hold', 'on hold
(from parking)', 'parked', 'parked as complete', or 'parked and
released'.
You have passed on an incorrect status with the parameter
<ZK>InvoiceDocStatus</> in the <ZK>Change</> method for altering a
provisional invoice document. This method can assign a different status
to an invoice document that is to be changed according to the following
rules:
Invoice documents to be changed that have the status 'on hold' can be
reassigned the status 'on hold', 'parked', or 'parked as complete'.
Invoice documents to be changed that have the status 'on hold (from
parking)' can be reassigned the status 'parked' or 'parked as complete'.
Invoice documents to be changed that have the status 'parked' can be
reassigned the status 'parked' or 'parked as complete'.
Invoice documents to be changed that have the status 'parked as
complete' can be reassigned the status 'parked' or 'parked as complete'.
Invoice documents to be changed that have the status 'parked and
released' can be reassigned the status 'parked' or 'parked as complete'.

System Response

The system will terminate the further processing of the invoice
document.

How to fix this error?

Make certain that the invoice document you are processing has one of the
above statuses.
If you want to change a provisional invoice document, make sure that you
reassign a valid status to the document to be changed. The values that
can be assigned via the parameter <ZK>InvoiceDocStatus</> are listed in
the parameter documentation for the <ZK>Change</> method.
