  Duplicate Entries: The most common cause is that there are duplicate entries in the database for a sequential number that should be unique.
  Data Migration Issues: If data has been migrated from another system, it’s possible that the sequential numbers were not properly adjusted to ensure uniqueness.
  Concurrency Issues: In a multi-user environment, two processes might attempt to create an entry with the same sequential number simultaneously.
  Configuration Errors: Incorrect configuration in the number range settings can lead to overlaps in sequential numbers.
  
  Solution:
  
  Identify Duplicates: Use database queries or transaction codes to identify where the duplicate sequential number exists. This may involve checking the relevant tables where the sequential numbers are stored.
  Correct Data: Once duplicates are identified, you can either delete or modify the duplicate entries to ensure that each sequential number is unique.
  Adjust Number Ranges: If the issue is related to number range configuration, you may need to adjust the number ranges in the configuration settings to prevent future duplicates.
  Review Data Migration Processes: If the error arose after a data migration, review the migration scripts or processes to ensure that they correctly handle sequential numbers.
  Implement Locking Mechanisms: If concurrency is an issue, consider implementing locking mechanisms or using transactions to ensure that sequential numbers are generated in a controlled manner.
