SAP FIORI FACT SHEET ARCHITECTURE
The following figure shows the architecture of the Fiori FACT SHEET.
Fact sheets run only on an SAP HANA database and require an ABAP stack.
For the fact sheets, the ABAP front-end server contains the UI layer with the central UI component and the product-specific UI components for the products used (for example, ERP-FIN, CRM, SCM) as well as SAP Gateway. The central UI component contains for example the SAP UI5 control library and the SAP Fiori launchpad.
The front-end server has read access to the ABAP back-end server through a trusted RFC connection. The ABAP back-end server contains the SAP Business Suite with the business logic, search models, OData services, and the model provider.
