• What is the cause and solution for SAP error message ESH_ENG_CDSVAL_ES057 - 'hidden': no ES-Connector will be generated! ?

  The SAP error message ESH_ENG_CDSVAL_ES057 indicates that there is an issue with the generation of an Enterprise Search (ES) connector in the context of Core Data Services (CDS) views. This error typically arises when the system is unable to generate a connector for a specific CDS view due to certain conditions not being met.
  Cause:
  
  Hidden Fields: The error message specifically mentions "hidden," which suggests that there are fields in the CDS view that are marked as hidden. Hidden fields cannot be used in the ES connector generation process.
  Incompatible Data Types: If the CDS view contains fields with data types that are not supported for ES connectors, this can also lead to the error.
  Missing Annotations: The required annotations for the CDS view might be missing. Annotations are essential for defining how the data should be treated in the context of Enterprise Search.
  Technical Issues: There could be underlying technical issues with the CDS view or the system configuration that prevent the connector from being generated.
  
  Solution:
  
  Review the CDS View: Check the definition of the CDS view for any fields that are marked as hidden. If these fields are not necessary for the ES connector, consider removing or modifying them.
  Check Data Types: Ensure that all fields in the CDS view have compatible data types that can be used in the ES connector.
  Add Required Annotations: Make sure that the necessary annotations for Enterprise Search are included in the CDS view. This may include annotations like @Search.searchable or @Search.defaultSearch.
  Test the CDS View: Execute the CDS view in the ABAP environment to ensure it is functioning correctly and returning the expected results.
  Re-generate the ES Connector: After making the necessary changes, attempt to regenerate the ES connector for the CDS view.
