• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2136 - The assignment of an authorization field to a node field does not exist ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2136 indicates that there is an issue with the assignment of an authorization field to a node field in the context of the Enterprise Search (ESH) Object Model. This typically occurs when the system is trying to access or utilize a field that has not been properly configured or assigned in the authorization model.
  Cause:
  
  Missing Assignment: The error usually arises when there is no valid assignment of an authorization field to a specific node field in the object model. This can happen if the configuration was not completed correctly or if there were changes made to the object model that were not reflected in the authorization settings.
  Configuration Issues: Changes in the underlying data model or object model without corresponding updates in the authorization settings can lead to this error.
  Transport Issues: If the object model was transported from one system to another (e.g., from development to production), the necessary authorizations may not have been transported correctly.
  
  Solution:
  
  
  Check Object Model Configuration: 
  
  Go to the ESH Object Model configuration and verify that all necessary fields are correctly assigned. Ensure that the authorization fields are properly linked to the node fields.
  Use transaction code /IWFND/MAINT_SERVICE to check the service and its configuration.
  
  
  
  Update Authorizations:
  
  If you identify that an authorization field is missing, you will need to create or update the assignment in the authorization settings.
  Use transaction SU21 to manage authorization objects and ensure that the necessary fields are included.
  
  
  
  Rebuild the Object Model:
  
  If the configuration appears correct but the error persists, consider rebuilding the object model. This can sometimes resolve inconsistencies.
  Use transaction /IWFND/MAINT_SERVICE to regenerate the object model.
  
  
  
  Check Transport Requests:
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included in the transport request.
  If something is missing, you may need to manually adjust the configuration in the target system.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific version of ESH you are using. There may be specific patches or updates that address this issue.
