SAP S/4HANA Overview Pages are used to provide users with a consolidated view of critical information and key performance indicators (KPIs) in a business context. You can create these pages and design their user interfaces using UI annotations in combination with SAP Fiori Elements. UI annotations provide metadata that defines how data should be displayed and interacted with on these Overview Pages.
Here's a step-by-step overview of how to develop an SAP S/4HANA Overview Page using UI annotations:
1. Define Your Data Source:
Identify the data source or OData service that will provide the data for your Overview Page. This could be a standard SAP service or a custom service you've created.
2. Choose a Template:
Decide on the template you want to use for your Overview Page. SAP Fiori Elements offers several templates like Analytical List Page (ALP), Object Page, and more.
3. Create a CDS View or Query:
If you're building a custom Overview Page, create a Core Data Services (CDS) view or a query that defines the data structure and logic for your page. Ensure that it exposes the necessary data fields.
4. Add Annotations:
Use UI annotations to define how the data should be displayed and interacted with on the Overview Page. Annotations are typically added to the CDS view or query
5. Design Your Overview Page:
Use the SAP Fiori Elements templates to automatically generate the user interface based on your annotations. Customize the generated user interface as needed to match your requirements.
Configure KPIs, charts, and tables to display data according to your annotations.
6. Test and Refine:
Test your Overview Page to ensure that data is displayed correctly and that interactions work as expected. Make refinements as needed.
7. Deploy and Publish:
Once your Overview Page is complete, deploy it to your SAP S/4HANA environment. Ensure that the necessary roles and authorizations are assigned to the users who need access to the page.
8. Monitor and Maintain:
Regularly monitor the performance of your Overview Page and update it as your business requirements evolve.
It's important to note that developing SAP S/4HANA Overview Pages using UI annotations and Fiori Elements is a collaborative effort that often involves functional and technical teams working together to define the data model, annotations, and user interface design. Additionally, SAP may release updates and improvements to the Fiori Elements templates and annotations, so staying current with SAP documentation and best practices is essential.
