About Unique ID Numbers

From InSite

Each time you create a new record, InSite programmatically assigns a unique identification number to it. Each number is prepended with a single letter denoting its type. For example, each Incident record is prepended with the letter "I" followed by a hyphen and the numeric portion of the Incident record number. Each Problem record is prepended with the letter "P" and each Change record is prepended with the letter "C".

The unique identification number that is assigned to the record remains with it throughout the lifecyle of the record and after the record is closed and stored in the database. No identification numbers are ever duplicated.
