Custom Field Settings: Maintain History

When you select the Maintain history check box, changes in the effective date for that custom field will be tracked. If you generate a report that allows you to specify an as-of date and you’ve included a custom field that maintains history, the value of the custom field at the time of the as of date will be honored.

For example, let’s say you have a security custom field called Security Rating that maintains history. Security ABC has a Security Rating of Good with an effective date of 1/1/2014 and a Security Rating of Excellent with an effective date of 3/15/2014.

If you generate a Holdings report that includes this column as of 1/1/2014, the column will display Good for the security ABC. If you generate the Holdings report as of 4/1/2014, the column will display Excellent.
