Use this tab to specify the project’s resource default rate type for new assignments and whether resources can be assigned to the same activity more than once.
Assignment Defaults
Click 
to select the default rate type for new resource and role assignments in the project. The rate type determines which price/unit is set on the assignment. For resources, the list corresponds to the rate types defined in the Rate Types tab in the Admin Preferences dialog box when P6 Professional is connected to a P6 Professional database and in the Application Settings in P6 when connected to a P6 EPPM database. For roles, the list corresponds to the rate types defined in the Prices tab of the Roles dialog box. This setting does not affect existing assignments.
Drive activity dates by default: Mark to allow the assignment finish dates to roll up to the activity finish dates for new resource and role assignments. Clear to allow the resource/role dates to be independent of the activity dates. P6 Professional marks this option by default.
Resource Assignments
Resources can be assigned to the same activity more than once: Mark to allow the same resource to be assigned to an activity more than once.
