  Conversion Logic: The logic used in the conversion program may not be correctly differentiating between the old and new accounts.
  
  Solution:
  
  Review Mapping Configuration: Check the mapping of old G/L accounts to new G/L accounts in the migration settings. Ensure that each old account is mapped to a different new account.
  Correct Data Entries: If you find that the same account has been assigned, correct the entries in the mapping table or configuration.
  Consult Documentation: Refer to the SAP documentation or guidelines for the migration process to ensure that you are following the correct procedures.
  Test Migration: After making corrections, run a test migration to ensure that the error does not occur again.
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide guidance specific to your system configuration.

  Documentation: Review SAP Notes and guides related to the migration from classic G/L to new G/L, as they may provide insights into common issues and their resolutions.
