• What is the cause and solution for SAP error message FAGL_MIG273 - No uniquely assigned account exists for old account &1 ?

  The SAP error message FAGL_MIG273 indicates that during the migration process from the classic General Ledger (G/L) to the new G/L, the system could not find a uniquely assigned account for the old account specified in the error message. This typically occurs when there are issues with the mapping of accounts between the old and new G/L systems.
  Cause:
  
  Missing Mapping: The old account does not have a corresponding new account assigned in the mapping table.
  Multiple Assignments: There may be multiple new accounts assigned to the old account, leading to ambiguity.
  Configuration Issues: The configuration settings for the migration might not be set up correctly, leading to inconsistencies in account assignments.
  Data Inconsistencies: There may be inconsistencies in the master data or the migration data that prevent the system from finding a unique mapping.
  
  Solution:
  
  
  Check Account Mapping:
  
  Go to the transaction code OBY6 (or the relevant transaction for your version) to check the mapping of old accounts to new accounts.
  Ensure that each old account has a unique new account assigned.
  
  
  
  Review Migration Settings:
  
  Check the migration settings in the configuration to ensure that they are correctly set up for the transition from classic G/L to new G/L.
  Ensure that the migration program is correctly configured to handle the accounts.
  
  
  
  Correct Data:
  
  If there are multiple new accounts assigned to the old account, you will need to resolve this by either consolidating the accounts or ensuring that only one new account is assigned.
  If there are missing mappings, create the necessary mappings in the configuration.
  
  
  
  Run Migration Again:
  
  After making the necessary corrections, rerun the migration process to see if the error persists.
