History: System Tracker Field

            ! System Tracker Field

!!ItemID
In later versions of the 1.9.x series, ItemID was available via this field type. In version >=2.0, please see ((Auto-Increment Field))

This field is used internally. For instance, when you decide that a tracker is rated, a system field for each item of this type will be automatically created. The field name will be 'Rating'.
