  Cause:
  
  Missing Connector: The primary cause of this error is that the CDS entities in question are not linked to a search connector. Connectors are necessary for integrating CDS views with the search framework, allowing the data to be indexed and made searchable.
  Configuration Issues: There may be configuration issues in the Enterprise Search settings or the specific CDS view definitions.
  Transport Issues: If the CDS views were transported from one system to another, the connectors may not have been transported or configured correctly.

  Ensure that the relevant CDS entities are assigned to the appropriate connectors.
  
  
  
  Create or Assign Connectors:
  
  If the connectors do not exist, you may need to create them. This can typically be done in the SAP Gateway or Enterprise Search configuration.
  Use transaction ESH_COCKPIT to manage and configure connectors for your CDS entities.
  
  
  
  Check CDS View Definitions:
  
  Review the definitions of the CDS views to ensure they are correctly defined and that all necessary annotations for search are included.
  Make sure that the CDS views are marked for search and that they have the appropriate annotations.
  
  
  
  Re-indexing:
  
  After making changes, you may need to re-index the search to ensure that the changes take effect. This can be done through the SAP Enterprise Search administration tools.
