defined so that accounts in your lower level detail budgets roll up into the same summary accounts as the detail accounts in your controlling master budget. A common misconception is that the detail budgets somehow roll up to the master budget by definition, this is not true. You must actually budget to a detail account in the master budget, this then serves as the controlling amount for the detail budgets. Master/Detail budgets are used in the budgeting process to control
Authority and identify budgets that exceed control limits. They are not intended for reporting purposes.
