This error typically occurs in the context of the SAP Enterprise Search or the SAP HANA Search framework, where object models are defined for search purposes.
  Cause:

  Check the settings for the node attribute group and ensure that they are unique.
  
  
  
  Transport Management:
  
  If this error occurs during a transport, check the transport logs to see if the object model was already present in the target system.
