To implement an Unmanaged Query<\/strong> in RAP, you follow a structured approach involving several key steps. First, you create a CDS view entity<\/strong> that defines the data structure or projection you want to expose. Then, you define a Query Behavior Definition<\/strong> for that view using the keyword define behavior for ... implementation in class ... unmanaged<\/code>. This tells RAP that you will provide your own implementation logic rather than relying on managed data handling.<\/p>\n

Next, you create an ABAP class<\/strong> (the query provider class) that implements the interface IF_RAP_QUERY_PROVIDER<\/code><\/strong>. The core method IF_RAP_QUERY_PROVIDER~SELECT<\/code><\/strong> must be redefined in this class. Inside this method, you write custom ABAP logic to retrieve data \u2014 it could be from a database table, an API, or even a legacy system. You then fill the result table and pass it back to the framework.<\/p>\n

This unmanaged approach is used when data retrieval cannot be handled by CDS-based managed queries (for example, reading from custom logic, calling RFCs, or combining different data sources). It provides greater flexibility at the cost of additional coding responsibility.<\/p>\n

Example structure:<\/p>\n

CLASS zcl_query_provider DEFINITION
\nPUBLIC FINAL CREATE PUBLIC.
\nPUBLIC SECTION.
\nINTERFACES if_rap_query_provider.
\nENDCLASS.<\/p>\n

CLASS zcl_query_provider IMPLEMENTATION.
\nMETHOD if_rap_query_provider~select.
\n” Custom data retrieval logic
\nENDMETHOD.
\nENDCLASS.<\/p>\n

This allows you to control how data is fetched and presented to consumers while still leveraging the RAP framework for OData exposure and metadata management.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
