  Solution:
  To resolve this error, you can take the following steps:

  Use transaction codes like SE16 or SE11 to check the relevant database table for existing records with the same key values. This will help you confirm whether the record indeed exists.
  
  
  
  Modify the Data:
  
  If the record already exists and you intended to update it, consider using an update operation instead of an insert.
  If you are trying to create a new record, ensure that the key values you are using are unique.
  
  
  
  Data Validation:
  
  Implement validation checks in your data processing logic to prevent attempts to insert duplicate records.
  If you are importing data, ensure that the source data does not contain duplicates.
  
  
  
  Error Handling:

  Consult Documentation:
