When a booking is exported to the accounting package, the accounting package processes it upon receipt. If a delay occurs in the accounting package, for example due to high load or a malfunction, and Zenvoices does not receive confirmation, the booking will be shown in Zenvoices under Export errors with the error message: "Call timed out".
This error message can be consulted via Bookings and then on the left under To export / Errors (provided the administrator has assigned this access right to the user).
Advice: Wait a few minutes and export the booking again so that the process is repeated.
Please note: it is possible that the booking has still been processed in the accounting package with a delay. In that case the accounting package may return an error during a new export attempt stating that the booking already exists.
The advice in that case is to delete the booking in the accounting package so it can be exported again.
