Don't allow an item to be in quarantine twice simultaneously!
At the moment it is possible for a serialised item to be booked into quarantine twice. For example a technician on site spots the fault during a job and puts the item straight into quarantine and the same fault gets picked up by the team checking in the equipment at the end of the job. When this happens the availability shows incorrectly because the system is seeing two item in quarantine when in fact there is only one.
The system either needs to calculate availability differently to account for this or it should prevent two quarantines being open at the same time (at very least a warning)
Preventing two simultaneous quarantines is preferable, because otherwise when an item is repaired, booking out the item from quarantine will not bring it back into availability if there is another un-noticed quarantine on the system.
Ideally when someone attempts to duplicate a quarantine there should be the option to edit the existing quarantine in case they have discovered a second fault for example.

I mentioned this to the team months ago and sadly it is still able to happen. This is absolute pain and must be a relatively quick fix I would think. Please fix this!
