In the last couple of years we've seen lots of innovations around SAP Fiori and with the release of S/4HANA there is no exception to this rule as Fiori is now a central part of the "Simplification Process" at SAP.
How does Fiori fit into the S/4HANA environment?
It all started with Fiori and the User Experience Renovation process in SAP. This change led to the innovation strategy, which is now transforming into the "simplification era" with S/4HANA. First, let’s think of S/4HANA not as a single component to be installed in the customers’ existing landscapes, but as a completely new product with a new vision on how customers make business and their underlying processes.
Once we have grasped this idea, we can start thinking on how to deploy this new solution.
Building Blocks in S/4HANA for the Frontend Server
The first step is to identify the required component versions and building blocks for the Frontend Server. With the previous versions of Suite on Hana (SoH) and Simple Finance we had some specific requirements, which differ from S/4HANA:
While the backend is only running on HANA DB, the frontend server supports also MaxDB and ASE as possible databases.
Maintenance Strategy/Minimum Versions for Frontend Server components in S/4 HANA
In general UI components can be patched independently by implementing notes or support packages, however, the duration of the maintenance period is 2 years from the first maintenance support package.Corrections for the UI add-on 2.0 for SAP NetWeaver are provided in Component Support Packages (CSP) as part of the Online Correction Support (OCS) and in accordance with the standard Support Packages and via SAP Notes.
You can find additional details about the general UI Maintenance Strategy in the following note 2217489 - Maintenance and Update Strategy for UI Add-On and User Interface Technology
Previous SAP Fiori product versions can be upgraded to the new UI 2.0 only if the required product version has been released to run on UI 2.0. You can find a detailed list on note 2200415 - Release of Fiori Product Versions for SAP UI Addon 2.0 / SAP_UI 7.50
Regarding Netweaver 7.5x there are restrictions for the required databases and minimal required versions:
Current Restrictions for Netweaver 7.5 can be found on note 2206460 - Release restrictions for SAP NetWeaver 7.5
Selecting a Frontend Server (FES) Deployment Option
With S/4 Hana the recommended deployment option is “Central Hub” because of the following reasons:
On the other hand, there are some considerations to be reviewed if you decide to go with this option:
Customers can choose between two network deployment models:
Internet Facing Deployment Recommendations
SAP recommends using Web Application Firewall capabilities in SAP Web Dispatcher or using an additional Web Application Firewall as first line of defense, especially when consuming SAP Fiori analytical apps or search capabilities over the Internet.
For an internet-facing deployment of mobile devices, you can use the SAP Mobile Platform Server, by doing this you can create a secure, efficient, and easy-to-manage mobile environment for SAP Fiori.
SAP Mobile Platform/Hana Cloud Platform Integration
It is also possible to integrate S/4HANA with SAP's Mobility Platform (SMP) to enable mobile scenarios embedding Fiori Apps on Kapsel/Cordova container or integrate S/4 Hana with Hana Cloud Platform mobile services (HCPms), which will enable enhancement scenarios.
UI Technology Troubleshooting
It is important to notice that during the process of testing Fiori apps end users or consultants may find errors while executing the applications. An important amount of errors can be related to the following components:
Therefore, SAP strongly recommends installing the latest UI 2.0 support package available before raising a message for an encountered issue as mentioned in note 1971640 - UI add-on 2.0 & 1.0 for SAP NetWeaver: recommendation install the most recent support pack...
Fiori Application Extensibility/Development
Currently SAP WebIDE (HCP) is the preferred tool to enhance or create new Fiori-like applications based on templates and SAP Best Practices, but support for Eclipse tools will continue. Just keep in mind that required UI libraries should be on version 1.30.x or higher.
Wrap-up
The journey into Fiori for S/4HANA seems promising and exciting, however reaching the goal might be challenging for many customers. Understanding the architecture, restrictions, and dependencies will prove to help obtaining a successful implementation.

Regarding Netweaver 7.5x there are restrictions for the required databases and minimal required versions:

Current Restrictions for Netweaver 7.5 can be found on note 2206460 - Release restrictions for SAP NetWeaver 7.5
Selecting a Frontend Server (FES) Deployment Option
With S/4 Hana the recommended deployment option is “Central Hub” because of the following reasons:
- Fiori UI software update cycles are decoupled from the backend system.
- FES is deployed as one instance, which can connect to several backend systems allowing the use of a centralized Fiori Launchpad.
- Routing mechanism is supported for several backend systems.
- FES can be implemented in segmented networks (e.g. DMZ) to serve security needs.
On the other hand, there are some considerations to be reviewed if you decide to go with this option:
- Additional NW ABAP System.
- User maintenance: User ID’s must be replicated from backend to frontend server.
- Network latency / response times.
Customers can choose between two network deployment models:
- Intranet Deployment – Customers use SAP Fiori apps in the intranet, meaning, inside their corporate network.
- Internet Facing Deployment – SAP Fiori apps are consumed from outside the corporate network requiring additional components.
Internet Facing Deployment Recommendations
SAP recommends using Web Application Firewall capabilities in SAP Web Dispatcher or using an additional Web Application Firewall as first line of defense, especially when consuming SAP Fiori analytical apps or search capabilities over the Internet.
For an internet-facing deployment of mobile devices, you can use the SAP Mobile Platform Server, by doing this you can create a secure, efficient, and easy-to-manage mobile environment for SAP Fiori.

It is also possible to integrate S/4HANA with SAP's Mobility Platform (SMP) to enable mobile scenarios embedding Fiori Apps on Kapsel/Cordova container or integrate S/4 Hana with Hana Cloud Platform mobile services (HCPms), which will enable enhancement scenarios.
UI Technology Troubleshooting
It is important to notice that during the process of testing Fiori apps end users or consultants may find errors while executing the applications. An important amount of errors can be related to the following components:
- Frontend UI Services
- Back-end UI Services
- SAPUI5 toolkit
- UI theme designer
Therefore, SAP strongly recommends installing the latest UI 2.0 support package available before raising a message for an encountered issue as mentioned in note 1971640 - UI add-on 2.0 & 1.0 for SAP NetWeaver: recommendation install the most recent support pack...
