¶ Customizing and Extending the List Report Component in SAP Fiori Elements
The List Report is one of the most widely used SAP Fiori Elements templates, providing users with a powerful and flexible interface to browse, filter, and analyze large data sets. Built on OData services and metadata annotations, the List Report enables rapid application development with a consistent UI and minimal coding.
However, real-world business scenarios often require customization and extension beyond the standard List Report capabilities. This article discusses the techniques, options, and best practices for customizing and extending the List Report component to meet specific business requirements while maintaining the benefits of the SAP Fiori Elements framework.
¶ Understanding the List Report Component
The List Report component offers:
- Dynamic Filtering: Via the Smart Filter Bar, allowing users to filter large datasets.
- Rich Tables: Displaying data with sorting, grouping, and pagination.
- Actions and Navigation: Supporting both standard and custom actions and drilldowns.
- Annotations Driven: Most of the UI and behavior are controlled via OData annotations.
While the standard List Report covers many use cases, businesses may need to:
- Add custom buttons or actions.
- Introduce additional fields or custom columns.
- Implement complex filtering logic.
- Customize the UI layout or behavior.
- Integrate custom validations or data processing.
- Modify navigation or data loading mechanisms.
¶ Techniques for Customizing and Extending the List Report
- Modify filter fields, table columns, and actions declaratively.
- Add or remove selection fields in the Smart Filter Bar.
- Configure table settings like visible columns or grouping.
Example snippet to add a new action button:
"sap.ui.generic.app": {
"pages": {
"ListReport|EntitySet": {
"component": {
"actions": {
"customAction": {
"template": "Button",
"text": "Custom Action",
"press": "onCustomActionPress"
}
}
}
}
}
}
- Leverage predefined extension points to inject custom UI controls without modifying the standard templates.
- Common extension points include header extensions, table columns, and filter bar extensions.
Example:
- Adding a custom column to the table via
TableExtension extension point.
- Implement the extension fragment in an XML file.
- Extend the standard List Report controller to add custom logic.
- Override or extend lifecycle hooks such as
onInit, onBeforeRebindTable, or custom event handlers.
- Implement custom filtering, validation, or event handling.
- Enhance OData service metadata with additional annotations.
- Define custom fields, semantic colors, or value helps.
- Use annotation files or CDS views for backend-driven UI extensions.
¶ 5. Custom Actions and Navigation
- Define custom actions in the manifest and implement their behavior in controller extensions.
- Customize navigation targets or add custom routing logic.
¶ Best Practices for Customizing and Extending
- Prefer Declarative Approaches: Use manifest and annotations where possible before resorting to code.
- Use Extension Points Provided by SAP: Avoid modifying standard templates directly.
- Keep Extensions Modular: Develop custom fragments or controllers separately for maintainability.
- Test Extensively: Check behavior across devices (desktop, tablet, mobile).
- Document Changes: Maintain clear documentation to support future maintenance and upgrades.
- Follow SAP Upgrade Guidelines: Ensure customizations don’t break on SAP UI5 or Fiori framework upgrades.
- Add a custom filter field to the Smart Filter Bar using manifest.json or annotations.
- Implement an extension fragment to handle additional input logic.
- Add a custom button in the toolbar to trigger a specific action.
- Extend the controller to handle button press events and manipulate data accordingly.
Customizing and extending the List Report component in SAP Fiori Elements enables organizations to tailor the powerful out-of-the-box capabilities to their unique business needs. By combining declarative customization, extension points, and controller enhancements, developers can deliver rich, responsive, and user-friendly applications while preserving upgrade safety and development efficiency.
Mastering these techniques is essential for SAP professionals aiming to build robust, scalable, and maintainable Fiori applications that maximize business value.
