  The SAP error message FAGL_LEDGER_CUST084 indicates that there is a potential inconsistency that may arise when activating the "Read Classic GL Accounting" indicator in the context of the General Ledger (G/L) accounting. This error typically occurs in the New General Ledger (New GL) environment when there are existing configurations or data that may conflict with the new settings.
  Cause:
  The error is triggered when you attempt to activate the "Read Classic GL Accounting" indicator for a ledger that already has data or configurations that are not compatible with the classic G/L accounting. This can happen due to:
  
  Existing Data: If there are already postings in the ledger that were made using the classic G/L, activating this indicator can lead to inconsistencies in how data is read and processed.
  Configuration Conflicts: The settings in the New GL may not align with the requirements of classic G/L accounting, leading to potential data integrity issues.
  Incompatibility with Other Settings: Other settings in the system, such as document splitting or segment reporting, may not work correctly if the classic G/L reading is enabled.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review Existing Data: Check if there are any existing postings in the ledger that could be affected by the change. If there are, you may need to analyze the impact of enabling the indicator.

  Seek Expert Advice: If you are unsure about the implications of this change, consult with an SAP expert or your SAP support team for guidance tailored to your specific configuration and business processes.
  
  
  Consider Upgrading: If you are using an older version of SAP, consider upgrading to a newer version that may have improved handling of G/L accounting and better compatibility between classic and new G/L functionalities.
