Configuring Survivorship Custom Date Fields

By default, the survivorship feature uses the Updated field to do comparison rules, such as Recent and History. You can configure any date or time field to use with the survivorship feature. For example, if you want to use the Contact birthday field as your comparison timestamp, you add the business service user property, CompareDateField_Contact, with the value, Birth Date. After these changes, make sure you compile the SRF and restart the Siebel Server.
