Fiori & UX
What is Fiori Front-End Server (FES)?
The ABAP system component that hosts the Fiori launchpad, UI5 libraries, and Gateway hub functionality.
It can be embedded in S/4HANA, which SAP now recommends, or deployed as a separate hub. FES versions must be compatible with the back-end release. FES updates affect all Fiori apps and need UI regression testing.
