To build CDS Views with Fiori like an expert, here are some steps you can follow:
Understand the Business Requirements: Before you start building a CDS View, it is essential to understand the business requirements. This will help you design a CDS View that meets the specific needs of the end-users.
Choose the Right View Type: Choose the appropriate view type based on the business requirements. For example, you can choose the Analytical view for complex analytical scenarios or the Projection view for simple data selection.
Define the Data Model: Define the data model in the Data Dictionary using the CDS object. This includes defining the entity types, fields, associations, and annotations.
Design the CDS View: Design the CDS View using the SAP Web IDE. Use the CDS editor to define the SELECT statement and define filters, calculated fields, and aggregations.
Enhance the View with Annotations: Enhance the CDS View with annotations to provide additional information to the end-users. Use the annotations to define the semantics of the view, the labels, and the descriptions.
Test and Validate the View: Test and validate the CDS View using the SAP Web IDE or the ABAP development tools. Check the data returned by the view, including the data types and the data volumes.
Publish the View: Publish the CDS View to the SAP Fiori Launchpad. Create a tile for the view and configure the tile settings, including the icon, the title, and the subtitle.
Monitor the View: Monitor the CDS View to ensure it is performing as expected. Use the SAP Fiori Launchpad to track the usage of the view and identify any issues.
By following these steps, you can build CDS Views with Fiori like an expert and deliver high-quality solutions to your end-users.
