This error typically occurs when the program attempts to insert or process data in a way that requires unique entries, but finds duplicates instead.

  Using SORT and DELETE ADJACENT DUPLICATES statements to remove duplicates from the internal table.
  Implementing logic to check for existing entries before inserting new ones.
  
  
  Check Index Definition: Ensure that the index defined in the program is correct and that it aligns with the expected unique constraints of the data being processed.
  Error Handling: Implement error handling in the ABAP code to manage situations where duplicates are encountered, possibly logging the issue for further analysis.
