SAP Fiori is the modern user interface (UI) framework designed to enhance the user experience across SAP applications. In SAP S/4HANA Cloud, Fiori plays a central role by providing intuitive, role-based access to business processes. However, every organization has unique needs, which makes customizing Fiori apps essential for optimizing business workflows and aligning the user interface with corporate standards. This article explores how Fiori apps can be customized in the SAP S/4HANA Cloud environment.
SAP Fiori apps are built using the SAPUI5 framework and follow design principles such as role-based access, responsiveness, and simplicity. With S/4HANA Cloud, users interact with hundreds of pre-delivered Fiori apps categorized by business roles, such as Accounts Payable Clerk, Sales Manager, or Production Planner.
Fiori apps in S/4HANA Cloud are typically standard, but SAP provides extensibility tools that enable users to adapt the apps without breaking the standard upgrade paths—a key requirement in cloud systems.
Adaptation at Runtime allows key users to modify the UI layout directly in the live system without development skills. Some of the changes include:
Tool Used: Adapt UI mode available within the Fiori Launchpad (for Key Users)
This method is non-invasive and upgrade-safe, ideal for simple personalization needs.
SAP S/4HANA Cloud supports extending the data model through the Custom Fields and Logic (CFL) app. You can:
Use Case Example: Adding a "Region Code" field to a Sales Order app and applying custom logic to validate it.
This includes a broader range of options such as:
All these extensions are handled within the S/4HANA Cloud system using built-in tools and are fully supported by SAP during upgrades.
For requirements not met by standard apps, organizations can create new business objects and design their own Fiori apps. This is done using:
This approach allows for complete flexibility but is still governed by the rules of the in-app extensibility framework to ensure upgrade compatibility.
For more advanced UI customizations, developers can use the SAP Business Application Studio (BAS) on SAP Business Technology Platform (BTP). With BAS, developers can:
This is ideal for scenarios where in-app extensibility is insufficient.
Customizing Fiori apps in SAP S/4HANA Cloud is a critical part of delivering tailored, user-centric solutions without compromising system stability or upgradability. SAP offers a powerful and flexible set of extensibility tools—from simple UI adjustments to full-fledged custom app development. By leveraging these capabilities wisely, organizations can enhance productivity, ensure compliance, and drive business success in a cloud environment.
