The unique number assigned to the record of the damage to, or loss of, an object or group of objects. The number should also refer to a file containing all written documentation about the damage or loss.
How to record
May include: a prefix to distinguish it from other reference numbers; the year; and a running number.
The same Damage/loss reference number can be used for one or more objects acquired together, but an object can only have one Damage/loss reference number.
