You use the Page Editor tool to add a value help UI to section fields on the Object Page of an SAP Fiori elements application. The Page Editor is a graphical user interface that allows you to configure and customize the UI elements of your application using annotations. You can access the Page Editor from the Application Information page or the Command Palette tool in SAP Business Application Studio12
To add a value help UI to a section field, you need to follow these steps:
Open the Page Editor for the Object Page of your app and expand the nodes Sections->Section Name->Subsections->Field Group Name->Form.
Select the field that you want to add a value help UI to and open the Property Sheet.
In the Property Sheet, scroll down to the Value Help section and enable the Value Help switch.
Choose the Value Help Type from the drop-down list. You can choose from Basic, OData, or Custom.
Depending on the Value Help Type, you need to provide additional properties, such as the Value List Entity, the Value List Path, the Value List Parameters, or the Custom Value Help Function34

Question # 18
What happens when you add a new projection to your project?
A.
A new service is added that exposes a view on underlying domain model entities.
B.
An external data model is added that represents data from another system.
C.
A new data model entity is added that describes a data structure.
D.
A new user interface application is added that displays data stored in the domain model.
When you add a new projection to your project, you are creating a new service that exposes a view on underlying domain model entities. A projection is a CDS data definition that defines a subset of fields or a join of entities from the domain model. A projection can also apply filters, aggregations, or calculations on the data. A projection is used to expose data to the service layer or the user interface layer1. A projection is not an external data model, a data model entity, or a user interface application.
