  Identify Duplicates: Check the data set being processed for duplicates. You can use SQL queries or data analysis tools to identify any duplicate entries that might be causing the issue.

  Review Configuration: Ensure that the configuration settings for the data migration process are correct. This includes checking any mapping or transformation rules that might lead to duplicates.
  
  
  Data Validation: Perform a thorough validation of the source data to ensure that it adheres to the expected format and constraints before attempting the migration again.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool or process you are using for any additional guidance or known issues.
  
  
  Testing: After making the necessary adjustments, conduct a test migration with a smaller subset of data to ensure that the issue has been resolved before proceeding with the full migration.
