This error indicates that the system cannot find a specified ledger in the configuration, which is necessary for processing transactions related to budgetary control.
  Cause:
  
  Missing Ledger Configuration: The specified ledger has not been defined in the system.
  Incorrect Ledger Assignment: The ledger may not be correctly assigned to the relevant organizational unit or fiscal year.
  Data Entry Error: There may be a typographical error in the ledger name or code being referenced in the transaction.
