Fiori Application Based on ABAP CDS

The development of SAP Fiori applications starts with the data modeling phase.

After the back-end developer has built ABAP CDS sources, he uses the odata.publish:true annotation to registers the Odata service in the backend. Then the developer publishes it to the sap gateway hub system using transaction /IWFND/MAINT_SERVICE.

FIORI Elements

After the user logged on to SAP WebIDE, he or she can start development by creating a new project. In order to use SAP Fiori elements, the new project should be based on a template.

List Report Application is one of the templates offered by Fiori Elements. It creates a Fiori application with a list display and is based on an Odata service and a CDS view.

The generated application is tested in SAP WebIDE by running the project in flpSandbox.

UI-Specific Annotations

UI-Specific annotations in the CDS view to influence the way the UI is generated.

Here are a few examples:

• Annotation @UI.headerInfo : Specifies a Caption for the list display.
• Annotation @Search.searchable: true enables a search dialog
• Annotation @UI.lineItem: This makes this field a column in the list display. The number after the addition position sets the position of the column.
• Annotation @UI.selectionField: adds a corresponding UI element to the selection dialog.
