• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2868 - Node field &1 (key field) is not referenced in a request field ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2868 indicates that there is a problem with the configuration of a data model in the SAP Enterprise Search (ESH) framework. Specifically, it suggests that a key field (denoted as &1 in the error message) is not being referenced correctly in a request field. This can occur in scenarios where the data model is expected to map certain fields but fails to do so.
  Cause:
  
  Field Mapping Issues: The key field is not properly mapped to a corresponding request field in the data model configuration.
  Data Model Configuration: There may be an inconsistency or error in the configuration of the data model, such as missing or incorrectly defined fields.
  Changes in Data Structure: If there have been recent changes to the underlying data structure or database tables, the data model may not have been updated accordingly.
  Transport Issues: If the data model was transported from one system to another, there may have been issues during the transport process that led to missing references.
  
  Solution:
  
  
  Check Data Model Configuration:
  
  Go to the ESH data model configuration in the SAP system.
  Verify that the key field is correctly defined and mapped to the appropriate request field.
  Ensure that all necessary fields are included in the data model.
  
  
  
  Update or Reconfigure the Data Model:
  
  If you find discrepancies, update the data model configuration to ensure that the key field is referenced correctly.
  You may need to add the key field to the request field mapping if it is missing.
  
  
  
  Review Recent Changes:
  
  If there have been recent changes to the data structure, review those changes to ensure that they are reflected in the data model.
  Update the data model as necessary to accommodate any changes.
  
  
  
  Check Transport Logs:
  
  If the issue arose after a transport, check the transport logs for any errors or warnings that may indicate problems with the data model configuration.
  
  
  
  Test the Configuration:
  
  After making changes, test the data model to ensure that the error no longer occurs and that the search functionality works as expected.
