  Key Violations: The data being imported may violate unique constraints defined in the target system, such as primary keys or unique indexes.
  
  
  Configuration Issues: There may be configuration settings in the data import process that do not allow for duplicates, leading to this error.

  Removing duplicates.
  Merging records if necessary.
  Ensuring that all required fields are populated correctly.
  
  
  
  Review Import Settings: Check the settings of the import process to ensure that it is configured correctly to handle duplicates if that is acceptable for your business process. This may involve adjusting settings in the data import tool or process.
  
  
  Error Handling: Implement error handling in your data import process to log and manage errors effectively. This can help in identifying issues quickly in future imports.
