• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2885 - There must be no more than one field of type &1 or &2 ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2885 indicates that there is an issue with the configuration of the object model in the SAP Enterprise Search (SAP ESH) system. Specifically, it states that there must be no more than one field of a certain type (indicated by &1 or &2) in the object model definition.
  Cause:
  This error typically arises when:
  
  Duplicate Field Types: The object model has been defined with multiple fields of the same type (e.g., multiple fields of type "string" or "date"). The system expects only one field of each type to avoid ambiguity in data retrieval and indexing.
  Incorrect Configuration: There may be a misconfiguration in the object model settings, where the same field type has been added more than once.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Object Model Configuration:
  
  Go to the SAP ESH configuration settings.
  Check the object model definition for the specific object that is causing the error.
  Identify fields of type &1 or &2 (as indicated in the error message) and ensure that there is only one field of each type.
  
  
  
  Modify the Object Model:
  
  If you find duplicate fields, remove or consolidate them so that only one field of each type remains.
  Ensure that the remaining fields are correctly defined and serve the intended purpose.
  
  
  
  Re-Indexing:
  
  After making changes to the object model, you may need to re-index the data to ensure that the changes take effect.
  Navigate to the indexing settings and trigger a re-indexing process for the affected object model.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the search functionality to ensure that the error no longer occurs and that the search results are as expected.
