Maintaining the Master Data Hierarchy 
For more information on the master data hierarchy concept, see
Master Data Hierarchy. See also Example: Master Data Hierarchy.To maintain the hierarchies, choose Master data
® Master data hierarchy ® Edit.Creating a master data hierarchy

If you enter a characteristic which has been created with the same data element and same domain as another characteristic, the hierarchy is valid for both characteristics because it has the same characteristic values. A list of the affected characteristics appears automatically in the lower part of the screen.
The next screen contains information about the hierarchy
If you select Visible system-wide, the current variant will be active in all the applications using the master data hierarchy maintenance,. Otherwise, the variant is only available in EC-EIS and EC-BP.
Position the cursor on a node and press
F4 to display the chargeable characteristic values. Select the desired characteristic value or an existing non-chargeable node.To enter a non-chargeable characteristic value which does not yet exist, choose Goto
® Maint.non-chrge.node.Each characteristic value may only occur once in a hierarchy variant. If a characteristic value is already contained in the hierarchy, it no longer appears as a possible entry. There are various functions in the Edit menu for adding new nodes:
A blank node is added on the same level as the selected entry.
A blank node is added on the level below the selected entry.
Several blank nodes are added on the same level as the selected entry.
Several blank nodes are added on the level below the selected entry.
A range is added on the same level as the selected entry.
A range is added on the level below the selected entry
With these last functions you can enter a value range, that is from characteristic value X to characteristic value Z.
Changing, displaying, copying and deleting a master data hierarchy
You perform the functions Change, Display, Copy and Delete in a similar way to Create.
You can copy an existing hierarchy from one hierarchy variant into another, and use it as the basis for a new hierarchy. You can then change it as necessary.
When you change a hierarchy, you can add new nodes, remove existing ones and also cut out and insert parts of the hierarchy.
You can search for certain values in the hierarchy by choosing Edit
® Find ® Characteristic value. You can also see the relationships between the nodes by positioning the cursor on a node and searching according to parent, 1st child and so on.In order to facilitate working with the hierarchy, you can expand and collapse the groups and subgroups by clicking on the plus and minus signs.
On the initial screen, you can delete a hierarchy variant that is no longer required.
