Variables for Hierarchies and Hierarchy Nodes 
Variables for Hierarchies and Hierarchy Nodes
If you define a form or report with a characteristic hierarchy, the system asks you to enter a specific hierarchy variant or hierarchy node (see
Entering and Using a Hierarchy Node). In this field you can also enter a variable instead of a fixed value.Variables for hierarchies and hierarchy nodes work just like variables for characteristic values. For more information, see
Variables for Characteristic Values.Special features of variables for hierarchies
When you maintain a local variable for a hierarchy node, you only need to enter the replacement type. If you want, you can also enter an identifier for the variable. For variables for hierarchies, you can only maintain an identifier, since replacement is automatically mandatory.
When you maintain global hierarchy variables and choose replacement type "2" (replacement by manual entry), be sure to enter "3" (Mandatory variable which is not blank (technical)) in the field Optional entry.
