How is the parameter defined in a CDS view entity?

In a Core Data Services (CDS) view, parameters are defined within parentheses following the view name. This syntax allows the CDS view to accept dynamic values at runtime, which can be used in queries to filter or manipulate data based on the input provided by the user or calling application.

Defining parameters in this manner enhances the flexibility and reusability of the CDS view, enabling it to cater to various scenarios, such as filtering results according to specific criteria or providing different outputs depending on the parameters supplied. This feature is particularly useful in creating dynamic reports and analytics, where end-users can specify criteria without requiring changes to the underlying view definition.

In contrast, defining a parameter as a variable in the SELECT statement or as a constant in the WHERE clause would not align with the CDS view parameter creation syntax. Similarly, while an inline declaration serves its purpose in other contexts, it does not describe how parameters are structured in CDS views specifically. Thus, the definition of parameters directly following the view name in parentheses is the correct and standard way to implement them in this environment.
