In Salesforce CPQ, the Order Management plugin functionality provides flexibility in customizing the default package behavior, including the ability to set the activation date for orders. This feature allows for greater control over the order management process, enabling organizations to align the activation dates of their orders with their specific business requirements. By overriding the default behavior, businesses can ensure that the activation dates are set in a manner that is consistent with their operational workflows, contractual obligations, or customer agreements. This capability is part of Salesforce CPQ's broader set of features designed to provide customizable solutions to complex quoting and order management challenges.
