Can I edit resource breakdown structures on a project?

Yes. If a planning resource breakdown structure allows resource changes at the project level, you can add resources while working on the project or financial plan. However, you can't add resource formats or make any other changes at the project level.

As actual amounts are incurred for a project, if you want resources to be automatically added to the primary planning resource breakdown structure when it allows changes at the project level, then select the Automatically add resources on incurring actual amounts check box in the Manage Planning and Billing Resource Breakdown Structures page.

Tip: The Automatically add resources on incurring actual amounts option isn't applicable for projects that are enabled for budgetary controls. Projects enabled for budgetary control need a stringent control on resources incurring project costs.
