Hotel operation Coral 3 V14.67 (yes, it's not supported), but system has been in for over 10 years without an issue.

They use #1980 to set and check wakeup calls. They can set a wakeup call at 2pm and by 5pm the data is not there when they recheck it. They keep re-entering the data and 3-4 hours later it's gone. They do not use check in/out in SFE6.

Any thoughts
