  The SAP error message FMFG880, which states "Duplicate account group entries not allowed," typically occurs when there is an attempt to create or modify an account group in the Financial Management (FM) module that already exists in the system. This error is related to the configuration of account groups, which are used to categorize accounts in the financial system.

  Solution:
  
  
  Check Existing Account Groups: 
  
  Go to the transaction code OBD4 (or the relevant transaction for your version) to view existing account groups. Check if the account group you are trying to create already exists.

  Data Cleanup: 
  
  If the error is due to data migration, review the data for duplicates and clean it up before attempting to create or modify account groups.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or consult with your SAP Basis or Functional team to ensure that you are following the correct procedures for account group creation.
  
  
  
  Check for Customizations: 
  
  If your organization has custom developments or enhancements, check if any custom logic is causing this error.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as OBD4 for account group maintenance and OBD2 for account group assignment.
