Time-dependent Hierarchies 
Time-dependent Hierarchies
Use
In the InfoObject characteristic maintenance you determine whether or not a hierarchy may be time-dependent. You define either that the entire hierarchy should be time-dependent or that the hierarchy structure (each individual node relationship) should be time-dependent.
If you only need the hierarchy each month, you should create the entire hierarchy as time-dependent. However, if you only need the current view on the hierarchy, you should not create it as time-dependent. Of course you can activate it as often as you like.
Entire Hierarchy Time-dependent
If an entire hierarchy is time-dependent, this means that there are versions of the hierarchy that are valid for one time interval each. The system automatically uses the current valid version in this case.
You can make the hierarchy time-dependent, within the context of an area restructuring of your business, for the characteristic Main Region, in order to compare them with one another at different times in a query.

The hierarchy that is valid currently is uniquely identified by the technical name and the from – to date. The time-dependent hierarchies that have been created, are displayed, along with the current ‘To date’ in the InfoObject tree under the InfoObject belonging to it. When a query is executed, the valid hierarchy is found using the query key date.
You can also work in the individual columns of a report structure with fixed date values, for example to. Compare the "Main area North" in the hierarchy of 31.05.2000 with "Main area North" in the hierarchy of 01.06.2000 (simulation).
Time-dependent Hierarchy Structures
If the hierarchy structure is time-dependent, the hierarchy is set up on the current key date or on the key date defined in the query.
You can assign an employee to different cost centers at different times within the context of a restructuring.
In the hierarchy display (Hierarchy
® Context Menu (right mouse button) ® Display hierarchies) every node and every leaf is marked with a date symbol. All hierarchy nodes are displayed. Nodes that are hung according to time-dependency in different places in the structure can, therefore, appear more than once. Double-clicking on the nodes displays the validity period of the node relationship.By double-clicking on the node in this example, you would be able to see that ‘Jones’ is assigned to the region USA from 01.01.99 to 31.05.99, and to the region Puerto Rico from 01.06.99 to 31.12.99.
