Whenever a Resource Plan is created, Cost Plan is automatically created for it. How do we disable this behavior?
The Out of the box Business Rule called "Create Cost Plan" automatically creates Cost Plans upon creation of Resource Plans.
Deactivating this Business Rule will not create Cost Plan when Resource plan is created.
We do not recommend disabling Out of the Box Business Rules as we are not sure of the impact this would have.
Deactivating the Business Rule will be considered as customization.
