Global Hierarchies – Key Points
Global (or universal) hierarchies are any characteristic hierarchies that are maintained centrally in the app Manage Global Hierarchies.
You can create new hierarchies or copy from existing ones.
You can import and export hierarchies through worksheet files (from MS Excel for example).
You can import SAP S/4HANA hierarchies as a node into a consolidation hierarchy
(for example: an SAP S/4HANA profit center hierarchy can be imported as a node into a consolidation profit center hierarchy).
Global Hierarchies are stored in a central table and can be consumed by Fiori analytical apps at run time.

Key Benefits of Global Hierarchies

- Unified way to maintain hierarchies for different master data objects like Bank Account, Cost Center, Profit Center, Functional Area, Financial Statement Version, Product, and Consolidation related objects.
- Time-dependent hierarchies: If there is a change in the hierarchy, for example, one consolidation unit belonging to one node has to be moved to another node; the same hierarchy can be used in a different time frame, and the report will reflect the new change.
- Single dashboard to control hierarchies.
Use Global Hierarchies for Legal and Management Consolidation Reporting

Users can create multiple hierarchies for the same group reporting dimension to meet various business requirements. For example, a consolidation unit can have a legal as well as a management consolidation roll-up that can be used in consolidation reports.
Users can also generate a matrix-like report by selecting two hierarchies of different dimensions and placing them in rows and columns respectively, for example, consolidation unit by region in rows and profit centers by line of business in columns.

Using the Manage Global Hierarchies app you can also create reporting item hierarchies.

Compared to a mere FS item, a reporting item can be enhanced by assigning it a set of selection criteria of specific data, such as FS items, consolidation units, document types, and subitems.
At group report runtime the reporting item value is calculated.
You can arrange reporting items in reporting item hierarchies as shown in the figure above.
There are five delivered reporting item hierarchies:
X1 Statement of changes in equity
X2: Statement of cash flow
X3: Statement of comprehensive income
X4: P&L by function of expense
X5: IC reconciliation.

Based on the hierarchies of consolidation units, profit centers, and segments, you can display the data for these organizational units eliminated and consolidated hierarchically.
