Budget Milestone Alert Configuration Dialog Box
Budget Milestone alerts notify specified employees when amounts spent or percentages of budget spent for selected project plans reach or exceed milestone amounts or percentages. (Opportunity plans do not have actual amounts charged to them and do not have baselines, so Budget Milestone alerts do not apply to them.) The alert is triggered by the process server.
You can restrict the alerts to specific accounts and/or vendors you want to monitor. You can also notify recipients when a plan's baseline changes.
