The Resources Assignments area enables you to view a customized list of resource or role assignments based on the filters you assign to the view. Using this view, you can analyze assignment unit and cost values and make any necessary modifications to the assignment data. You can also view unit and cost values in a spreadsheet based on a specified timescale using the spreadsheet. In addition, you can extend your customized view by displaying the Gantt chart, which is a graphical display of the start and end dates for the resource assignments.
