Editing Hierarchies

Prerequisites

You have created a hierarchy for the required hierarchy basic characteristic (seeCreating Hierarchies).

Procedure

You can create hierarchies in two ways: Either from the SAP Easy Access Menu or in the Data Warehousing Workbench from hierarchy maintenance.

On the SAP Easy Access screen, choose Modeling → Master Data Maintenance → Hierarchies. The Initial Screen Hierarchy Editing dialog box appears. For more information, see section "Accessing from Editing Hierarchies".
You are in the Data Warehousing Workbench in the Modeling functional area. You can access hierarchy editing in the following ways:
- You can select an editing function in the context menu of a hierarchy in the InfoObject tree.
- In the Data Warehousing Workbench, you can call hierarchy maintenance in the toolbar by choosing Edit Hierarchies.

Access from InfoObject tree

In the Data Warehousing Workbench under Modeling, choose the InfoObject tree.
If you have assigned the hierarchy basic characteristic to an InfoObject catalog, select the corresponding InfoObject catalog for an InfoArea.
If the hierarchy basic characteristic does not belong to an InfoObject catalog, choose the InfoArea Unassigned Nodes and the InfoObject Catalog Unassigned Characteristics.
Select the characteristic hierarchy you want to edit and choose an editing function in the context menu. The following table gives you an overview of the available functions:

Editing functions

Function	Information
Display	The Display Hierarchy screen appears.
Change	The Change Hierarchy screen appears.
Copy	If several versions of the hierarchy are available, the Selection of Hierarchy Object Version dialog box appears. Choose the variant you want to use. The Save Hierarchy As dialog box appears. Enter a hierarchy name. If the hierarchy is version or time dependent, enter the hierarchy version and the validity date (seeHierarchy Properties). You can enter descriptions (short, medium and long) for the hierarchy that you want to copy.
Delete	Confirm the prompt if you do actually want to delete the hierarchy.
Activate	The system notifies you of whether activation was successful. In cases where it is not possible to activate the hierarchy, a dialog appears with the error log. If the hierarchy is already used in an aggregate, you can choose whether you want to activate the hierarchy directly and thereby delete the aggregate whether you want preselect the hierarchy for activation. In the latter case, you need to run the change run for this hierarchy. This updates all the aggregates contained in the hierarchy and activates the hierarchy. (SeeSystem Response Upon Changes to Master Data and Hierarchies)

Access from Edit Hierarchies

In the Data Warehousing Workbench toolbar, choose Edit Hierarchies. The Initial Screen: Hierarchy Editing appears with a list of all the hierarchies in your BW system.
You can restrict the list to hierarchies for a particular characteristic. Input help is available for the Restriction to Hierarchy Basic Characteristic field. After selecting the required hierarchy basic characteristic, choose Filter.
If you want to see details about a hierarchy, choose Details. A dialog box appears which contains the following entries:
- Internal hierarchy ID
- Short description
- Hierarchy name
- Hierarchy type
- InfoObject
- Version
- Valid to
- Valid from
- Source system
- Request no.
- Person responsible
- Number of levels in hierarchy
- Largest node ID of hierarchy
- Hierarchy is consistent
- Root node ID
- Language key
- Medium description
- Long description
Select the hierarchy you want to edit and then choose an editing function from the table above: Change Hierarchy, Display Hierarchy, Delete Hierarchy, Copy Hierarchy, Activate Hierarchy.
The Create Hierarchy function is also available (seeCreating Hierarchies).
