  Cause:
  The error is caused by the presence of multiple entries in the source data that have the same combination of Old G/L and New G/L accounts. This can happen due to:
  
  Data Duplication: The source data may have been incorrectly populated, leading to duplicate entries for the same account combination.
  Incorrect Mapping: During the mapping of Old G/L accounts to New G/L accounts, if the mapping is not unique, it can lead to duplicates.
  Data Migration Issues: If the data extraction or transformation process did not handle duplicates properly, it could result in this error.
  
  Solution:
  To resolve the error, you can follow these steps:

  Adjust Mapping:
  
  Review the mapping of Old G/L to New G/L accounts. Ensure that each Old G/L account is mapped to a unique New G/L account. If necessary, adjust the mapping to eliminate duplicates.
  
  
  
  Re-run the Migration:
  
  After cleaning the data and adjusting the mapping, re-run the migration process to see if the error persists.
