  Cause:
  The error is usually caused by one of the following reasons:
  
  Unsupported Query Conditions: The query being executed includes conditions or operations that cannot be pushed down to the database. This can happen if the query involves complex calculations, unsupported functions, or certain types of joins that the underlying database cannot handle.
  Indexing Limitations: The data model may not be optimized for the specific query, leading to the inability to use certain indexes effectively.

  Review OData Service Implementation: If you are developing an OData service, ensure that the service is implemented correctly and that it adheres to the best practices for query handling.
  
  
  Consult Documentation: Refer to SAP documentation for SADL and OData services to understand the limitations and best practices for query design.
