The reason why the cost element report for planned revenues does not show any revenues at all is that the manual hierarchical revenue planning has no reference to cost elements. Manual hierarchical revenue planning is a type of revenue planning that allows you to plan revenues for WBS elements manually without using sales documents. Manual hierarchical revenue planning does not use cost elements as a basis for planning, but uses revenue elements instead. Revenue elements are a set of data that define the characteristics and properties of a revenue type. Cost element reports can only display data that is based on cost elements, not revenue elements.
