When you make entries to elements with links marked as Costed for individual employees using the Element Entries window, or for many employees at once using the BEE windows, you can at the same time supply costing information.
Information entered at this level overrides any information entered at other levels. For example, if an employee has costing information on record in a Cost Allocation flexfield segment at the organization or assignment level, an entry of timecard information in this segment at the element entry level overrides the organization or assignment-level information.
