The CRM Web UI (Web User Interface) is a core component of the SAP Customer Relationship Management system, offering users a rich, browser-based interface to interact with customer data, business transactions, and processes. For SAP-ABAP-CRM developers, enhancing the CRM Web UI is essential to tailor the interface to specific business needs, improve usability, and add custom functionalities beyond the standard SAP offerings.
This article explores key concepts, techniques, and tools for enhancing the CRM Web UI using ABAP and related technologies.
¶ Understanding the CRM Web UI Architecture
The CRM Web UI is based on the Model-View-Controller (MVC) architecture and typically uses Business Server Pages (BSP) with Web Dynpro components, along with UI components based on Component Workbench and Enhancement Frameworks.
- Model: Data layer representing business objects.
- View: UI components rendering data.
- Controller: Manages user actions and business logic.
Enhancements are mainly done in the component controller, views, or by adding custom components.
SAP provides a standard Web UI framework, but real-world business scenarios often require:
- Custom fields or tabs in business transactions.
- Additional validations or business logic.
- Customized navigation and menus.
- Integration with external systems.
- Improved layout and user experience.
Enhancing the CRM Web UI allows organizations to:
- Align the CRM system with unique business processes.
- Improve user productivity with tailored interfaces.
- Extend standard functionality without modifying SAP standard code.
- SAP CRM Web UI components are developed using the Component Workbench (transaction BSP_WD_CMPWB).
- Developers can enhance existing standard components by extending views or controllers.
- New views or GUI elements can be added to existing transaction UIs.
- Adding new UI elements or fields to standard views.
- Customizing the layout using the Layout Designer.
- Implementing additional event handlers in the view controller.
- Overriding or adding methods in component or view controllers.
- Implementing custom business logic triggered by user actions.
- Using methods like
IF_BSP_WD_VIEW~DO_ACTION for custom button handling.
- BADIs allow you to enhance standard processes with custom ABAP code.
- Many CRM Web UI components offer predefined BADIs for UI and data manipulation.
- Example:
CRM_UIU_BADI for UI enhancements.
- SAP's Enhancement Framework allows non-intrusive extensions.
- Extension Spots in Web UI components facilitate plug-in style enhancements.
- Use
Enhancement Implementation to add UI logic or fields without modifying original components.
¶ 6. Custom Fields and Tables
- Extending CRM data model with custom fields via the Business Object Layer (BOL) and UI integration.
- Maintain custom fields through transaction CRMC_UI_PROFILE or transaction CRM_ORDER UI configuration.
- Synchronize custom fields between backend and Web UI.
¶ 7. JavaScript and CSS Customization
- For advanced UI changes, custom JavaScript or CSS can be injected.
- Enhances user experience with dynamic behavior or styling.
- Managed through BSP application modifications.
-
Create Custom Field in CRM backend using transaction CRM_UI_PROFILE or Enhancement Framework.
-
Enhance the UI Component using BSP_WD_CMPWB by:
- Extending the standard view to add the custom field UI element.
- Implementing controller logic to handle data transfer.
-
Activate and Test the enhanced UI in CRM Web UI.

- Avoid modifying SAP standard code directly. Use enhancement techniques like BADIs and extension spots.
- Maintain separation of concerns: Keep UI logic in views/controllers, business logic in backend classes.
- Test enhancements thoroughly in development and QA before transporting to production.
- Document enhancements clearly for future maintenance.
- Use transport requests to manage changes across SAP environments.
Enhancing the CRM Web UI in SAP ABAP CRM is a powerful way to tailor the system to meet specific business requirements and improve the overall user experience. By leveraging SAP’s enhancement frameworks, component extensions, and ABAP programming techniques, developers can implement robust customizations without compromising system integrity or upgrade paths.
Mastering these enhancement techniques is vital for SAP CRM developers aiming to deliver personalized and efficient CRM solutions that truly support business goals.
