Add a Project Billing Item
Note: If you are submitting a billing item
                (time or expense) for a child project worker, the amount of the billing item
                recalculates the total project budget. If the child project worker billing amount
                exceeds the available project budget, you cannot submit the billing item. For more
                information about project workers, see Project Worker Engagements.
Note: You can view child
                worker engagement billing items on the parent project engagement's
                    Billing tab.
Note: Project worker engagements are
                billed similar to Staffing engagements.
Note: For projects that have at least
                one project worker child engagement configured with a time card, you cannot bill for
                non-time card positions.
