This error typically arises when the system encounters multiple entries that should be unique based on the defined key fields.
  Cause:
  
  
  Data Duplication: The primary cause of this error is the presence of duplicate records in the source data that are being migrated or transformed. This can happen due to:
  
  Incorrect data extraction processes.
  Data entry errors in the source system.
  Inadequate data cleansing before migration.
  
  
  
  Key Field Definition: The table group in question may have specific key fields that are expected to be unique. If the data being processed does not adhere to this uniqueness constraint, the error will be triggered.
  
  
  Solution:
  
  
  Identify Duplicate Records:
  
  Use SQL queries or data analysis tools to identify the duplicate records in the source data. You can group the records by the key fields and count occurrences to find duplicates.
  
  
  
  Data Cleansing:
  
  Once duplicates are identified, you need to decide how to handle them. Options include:
  
  Removing duplicates if they are not needed.
  Merging records if they contain complementary information.
  Correcting data entry errors.
  
  
  
  
  
  Adjust Migration Logic:
  
  If duplicates are valid in the context of your business logic, you may need to adjust the migration logic to handle them appropriately, such as by modifying the key fields or changing how records are processed.
  
  
  
  Re-run the Migration:
  
  After cleansing the data and ensuring that there are no duplicates, re-run the migration process to see if the error persists.
