Answer: The "RR" may change the account number on the order ticket to the correct number if the branch manager approves in writing
Explanation: According to the scenario described above, the error in the executed order can only be effected based on approval by the branch manager after being notified by the registered representative of the error in the order ticket. The official approval to effect the change in the error made in the account details must be put into writing by the branch Manager for privacy and documentation sake as making such change to an order ticket requires following due process.
