What does the annotation @Consumption.ValueHelpDefinition specify?

The annotation @Consumption.ValueHelpDefinition is used to specify a Core Data Services (CDS) view that serves as a source for value help functionality in ABAP programming. This functionality is essential for allowing users to select values from a predefined list when interacting with input fields in an SAP application.

When you designate a CDS view with this annotation, you are essentially creating a link between the data model and the user interface, facilitating a better user experience by presenting a curated list of valid entries related to the context of the main data entity.

While other options relate to aspects of value help, such as the definitions of entries or fields, they do not describe the exact purpose of the ValueHelpDefinition annotation, which specifically identifies a CDS view designed to generate the list used for selection. Thus, by using this annotation, you enable a robust and user-friendly selection mechanism directly connected to the backend data.
