This function makes it possible for you to report on selected parts of hierarchies, or so-called "hierarchy nodes".
To report on a hierarchy node, you need to enter a hierarchy node instead of a characteristic value for the desired characteristic when you define either the form or the report itself. You do this on the screen Characteristic values by pressing the icon.
when you drill down to that characteristic in the drilldown list, the system only displays those values that belong to the selected hierarchy node. For example, if you select the node "Wage costs" for the characteristic "Cost element", the report will only contain those cost elements that represent wage costs.
You can also select an entire hierarchy instead of just one node using the Choose hierarchy function.
