Project tasks are not closing when parent Project is closedDescriptionWhen a parent project is closed all of its related project tasks should close automatically, but they are not getting closed.Cause In OOB (out of box), Business Rule: "Task Active State Management" sets active field to false, after which Business Rule: "Process State Change" runs and closes all of its related project tasks. In customer's instance, Business Rule: 'Task Active State Management' is returning even before setting the active field to false. Because of which when Business Rule: "Process State Change" gets executed it does not meet this condition if(current.active.changesTo(false) and does not close the project tasks. The reason why "Task Active State Management" was returning before setting the active field is that close states were not defined. In customer's instance, for "state" field there was dictionary override and it was missing close_states and default_close_state. ResolutionChange the dictionary override for the "state" field to include close_states and default_close_state, something like close_states=3;4;7,default_close_state=3 After this change, closing the parent project closed all of its related project tasks
