I found an anomaly related with dynamic availability check.
when I create a reservation, there's a warning message "On the 12.11.2010, only 0 EA available".
I can ensure that there's enough quantity in unrestricted use stock, even after deducted by other reservations.
Any idea where should I check the configuration?
I've checked "Dynamic Availability Check" menu under Reservation, but there's nothing weird. I compared to the other client that works fine, and the configuration seems nothing different.
