Transactional apps are a core category within the SAP Fiori application portfolio. Designed to handle routine business transactions efficiently, these apps enable users to create, update, delete, and manage business data directly through an intuitive interface. Developing effective transactional apps is essential for organizations looking to streamline operational workflows and improve productivity.
Transactional apps focus on day-to-day operational tasks such as processing purchase orders, entering time sheets, managing inventory, or creating sales orders. Unlike analytical apps, which present aggregated insights, or fact sheets, which provide detailed object information, transactional apps allow users to perform direct data manipulation within SAP systems.
SAP Fiori transactional apps are primarily developed using SAPUI5, a JavaScript UI toolkit, and follow SAP Fiori design principles. Backend connectivity is commonly achieved using OData services that expose business entities for CRUD operations.
Begin by understanding the transactional process, user roles, and the required data interactions. Clear requirements ensure the app addresses specific business needs.
Design or reuse an OData service that exposes the relevant business entities and operations. This service will be the data source for the app.
Develop the UI components, such as forms, tables, and buttons, using SAPUI5 controls. Use data binding to connect UI elements to the OData model.
Use the OData model's methods like create(), read(), update(), and remove() to enable data manipulation from the frontend. Handle success and error callbacks for robust user feedback.
Implement input validation to prevent erroneous data submissions. Provide meaningful error messages and guidance for users.
Verify the app’s responsiveness and functionality across different devices to ensure a consistent user experience.
Deploy the app within the SAP Fiori Launchpad and monitor its usage and performance for continuous improvement.
