• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2593 - Node field &1 cannot be a key field because it is of type &2 (string) ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2593 indicates that there is an issue with the configuration of a node in the Object Model of the Enterprise Search (ESH) framework. Specifically, the error states that a field (denoted as &1) cannot be designated as a key field because it is of type &2 (in this case, a string).
  Cause:
  
  Field Type Mismatch: The field you are trying to set as a key field is of type string, which is not allowed for key fields in the context of the Object Model. Key fields typically need to be of a numeric type or a specific type that can uniquely identify records.
  Incorrect Configuration: The configuration of the Object Model may have been set up incorrectly, leading to an attempt to use a non-appropriate field as a key.
  
  Solution:
  
  
  Review Field Types: Check the data type of the field you are trying to use as a key. If it is indeed a string, you will need to either:
  
  Change the field type to a suitable type that can be used as a key (if possible).
  Select a different field that is of an appropriate type (e.g., numeric) to serve as the key field.
  
  
  
  Modify Object Model Configuration:
  
  Access the Object Model configuration in the SAP system.
  Identify the node where the error is occurring.
  Change the key field to a valid field that meets the requirements for key fields.
  
  
  
  Testing: After making the necessary changes, test the Object Model to ensure that the error no longer occurs and that the model behaves as expected.
