What's a burden schedule?
Establishes the multipliers that are applied to the raw cost of each expenditure item to calculate the burdened cost, revenue, or bill amount charged to a project.
Assign burden schedules to project types, projects, or tasks. The project type provides the default burden schedule for a project. You can override the default burden schedule for each project by using a schedule of multipliers negotiated for the project or task.
In planning, when using planning rates, you assign a burden schedule in the project or financial planning options. The set of resources and rates are global and have no project context from which to derive a burden schedule.
