  The SAP error message ESH_SQL_SEARCH055 indicates that the CDS (Core Data Services) connector specified does not have any references for the response table. This error typically occurs in the context of SAP's Enterprise Search or when working with CDS views in the SAP HANA environment.
  Cause:
  
  Missing or Incorrect Configuration: The CDS connector may not be properly configured to reference the required response table. This could be due to missing annotations or incorrect settings in the CDS view.
  Data Model Issues: The underlying data model may not have the necessary relationships or references defined, leading to the inability to retrieve data for the specified response table.
  Transport Issues: If the CDS view or its associated objects were transported from one system to another, there may be inconsistencies or missing objects in the target system.
