When you create a cost model, you can specify additional charges and discounts. Use cost model rules to specify the amount of these charges and discounts and the conditions under which they are applied.
Adding cost model rules When you add a cost model rule, you need to configure the action that you want the rule to perform and whether the rule depends or not on the cost of the project.
Modifying cost model rules When you modify a cost model rule, you can modify any of the settings that you configured when you added it to the system.
Deleting cost model rules If a cost model rule is attached to a cost model, deleting that cost model rule will affect the cost of all the active projects configured to use the cost model.
