The field is created automatically when a new record is saved, whether a completely new record or a copy of an existing record.

It consists of two parts: the date and time of the record creation, and the two letter code of the operator in subfield |o. Taken together these form a unique record number, as no operator can create two records simultaneously.

The field cannot be edited or deleted, and will only disappear if the entire record is deleted.
