  • Publication number: 20220358514
    Abstract: A customer relationship management (CRM) platform may use a sales opportunity object to store information about a particular sales opportunity. However, if the life cycle of the sales opportunity involves multiple distinct sales attempts separated by dormant periods, the CRM platform can store historical data associated with one or more earlier sales attempts in sales attempt objects linked to the sales opportunity object. By storing historical data associated with previous sales attempts in linked sales attempt objects, the CRM platform can retain the historical data while allowing the sales opportunity object to be updated based on a more recent sales attempt.
