It is mandatory that the user indicate a FIN/VIN in the order (some versions required entering information in additional fields, e.g. track numbers, serial numbers, etc.).
The quantity is limited to 1.
C90=Waiting for response
A VeDoc request is started:
Response to FIN/VIN (error=C05)
Check for theft or disabled marker (active=C91)
Response from model plate data (for model plate orders)
Response from lock data (mechanical or < DAS3 for key orders)
