  Solution:
  
  Check for Existing Records: Before creating or updating a record, ensure that you check if a record with the same key fields already exists. This can be done through a simple SELECT query.
  Data Cleanup: If duplicates exist in the database, you may need to clean up the data. Identify and remove or merge duplicate records as necessary.
  Modify Custom Code: If the error is caused by custom code, review the logic to ensure it properly handles existing records and avoids duplicates.
  Locking Mechanisms: Implement locking mechanisms to prevent concurrent processes from creating duplicates. This can be done using database locks or application-level locks.
