In which operand positions can you use an input parameter for a CDS view entity?

The correct choice involves using the input parameter of a CDS view entity as a value for the input parameter of another CDS view entity. This scenario illustrates the capability of CDS views to be modular and dynamic, allowing one view to utilize parameters specified in another. By passing input parameters between views, developers can create complex queries that are flexible and reusable. This facilitates not only the organization of code but also enhances performance by leveraging the power of parameters to return the relevant dataset.

This context emphasizes the role of input parameters in creating interdependent CDS views, which leads to a more efficient data retrieval process tailored to specific conditions.

Other options, while relevant to database querying, do not specifically align with the unique capabilities of CDS view parameters. For example, using LIKE% is a filtering condition that may not utilize an input parameter correctly in a CDS view context. Similarly, using CASE conditions and filtering in the WHERE clause are standard SQL practices that may also not specifically highlight the ability to use input parameters across different view entities.
