Which function can be used for filtering values in the WHERE clause of a CDS view entity?

In the context of Core Data Services (CDS) views in SAP, filtering values using the LIKE condition is an important functionality. The LIKE operator allows for pattern matching in character strings, enabling users to implement filters that can search for data that fulfills certain criteria, often with wildcard characters such as % (representing zero or more characters) and _ (representing a single character).

When you employ the LIKE operator within the WHERE clause of a CDS view entity, it enables robust querying capabilities, allowing developers to create more flexible and dynamic filters based on user requirements or data characteristics. This is especially useful in scenarios where you need to filter data based on partial matches or variations of a string.

The other options, while valid in certain contexts, do not effectively apply to filtering in the WHERE clause of a CDS view. Using a match function, for instance, may not be standard practice in the context of CDS view filters, and employing a CASE statement typically pertains to conditional logic rather than filtering. Therefore, option C is accurately identified as the correct answer, owing to its alignment with standard practices for filtering string values in CDS views.
