SAP Fiori represents the modern user experience (UX) for SAP software, designed to provide a simple, role-based, and responsive interface across devices. In SAP S/4HANA, Fiori apps play a critical role in enhancing user productivity by offering intuitive access to business processes. However, standard Fiori apps often require customization to better fit unique business requirements and workflows.
This article delves into the essentials of customizing SAP Fiori apps within SAP S/4HANA, covering the customization scope, techniques, tools, and best practices to help SAP professionals tailor the user experience effectively.
SAP Fiori apps are web-based applications built using SAPUI5 technology that provide a consistent, user-friendly interface for interacting with SAP S/4HANA business processes. They are role-based, meaning users see only the functionalities relevant to their job roles, improving efficiency and reducing complexity.
There are three main types of Fiori apps:
- Transactional Apps: Enable users to perform daily tasks like creating purchase orders or approving invoices.
- Analytical Apps: Provide real-time insights and visualizations for decision-making.
- Fact Sheets: Offer detailed information on business objects like materials, customers, or suppliers.
While SAP delivers a rich library of standard Fiori apps, businesses often need to:
- Adapt apps to specific organizational processes and data fields.
- Enhance UI elements for better usability.
- Integrate with custom backend logic or third-party systems.
- Add new features or workflows.
- Ensure compliance with corporate branding guidelines.
Customization ensures that Fiori apps are aligned perfectly with business needs, driving adoption and operational excellence.
SAP S/4HANA enables "Key User Extensibility," allowing business users or power users to customize Fiori app UIs without developer intervention. Using the SAP Fiori launchpad adaptation tools, users can:
- Add, hide, or rearrange UI fields and controls.
- Change labels and texts.
- Personalize layouts and themes.
- Adapt filters and tables.
This low-code approach accelerates customization and empowers users to tailor apps dynamically.
For deeper customizations, developers use SAP Web IDE or SAP Business Application Studio:
- Extending Standard Apps: Modify or enhance standard SAP Fiori apps by extending UI components or adding custom logic.
- Creating Custom Apps: Build completely new Fiori apps tailored to unique business scenarios using SAPUI5 frameworks.
- Modifying Backend OData Services: Adjust or create new OData services to expose or manipulate data required by the app.
- Enhance apps by embedding custom validations, business rules, or workflows using ABAP backend enhancements or cloud side extensions.
- Use SAP Cloud Platform Extension Suite for side-by-side extensions, enabling innovation without impacting the core S/4HANA system.
¶ 4. Theming and Branding
- Apply corporate branding by customizing colors, logos, and styles through the SAP Fiori theme designer.
- Ensure the look and feel are consistent with organizational standards, enhancing user acceptance.
- SAP Fiori Launchpad Designer: Configure tiles, catalogs, and groups on the Fiori launchpad.
- SAP UI5 Flexibility Services: Provide runtime adaptations like field changes and UI personalization.
- SAP Fiori Elements: Framework for creating apps based on metadata-driven UI, simplifying app creation and customization.
- ABAP RESTful Programming Model (RAP): Used for developing OData services supporting custom apps.
- Start with Standard Before Customizing: Leverage SAP standard apps and adapt minimally to reduce maintenance overhead.
- Use Key User Extensibility Where Possible: Empower business users to make UI changes without developer involvement.
- Maintain Clear Documentation: Track customizations for future upgrades and troubleshooting.
- Follow SAP UI5 and Fiori Design Guidelines: Ensure customizations are consistent with SAP’s UX principles.
- Test Thoroughly Across Devices: Since Fiori is responsive, verify app behavior on desktops, tablets, and smartphones.
- Plan for Upgrades: Design customizations to be upgrade-safe, using extension points and avoiding core code modifications.
- Increased User Adoption: Apps that align with user workflows boost productivity and satisfaction.
- Process Optimization: Tailored functionalities help automate and streamline business processes.
- Improved Data Quality: Customized validations and input controls reduce errors.
- Scalability: Extensions and custom apps evolve as business needs change.

Customizing SAP Fiori apps is vital for organizations aiming to fully leverage SAP S/4HANA’s capabilities while addressing unique business requirements. By utilizing SAP’s flexible extensibility options—from key user adaptations to full developer extensions—companies can create a personalized, efficient, and engaging user experience that drives better business outcomes.
SAP professionals skilled in Fiori app customization will play a crucial role in enabling digital transformation and enhancing enterprise agility in the SAP S/4HANA landscape.
