How to customize or rename the message triggered in Oracle Fusion ?

Summary:

While creating employee expenses, the expectation is at least one employee bank account should be active. If the employee tries to create an expense report without a valid bank account it should error, this is a set up under Manage Payments --> User Validation. We also get the error, but the error message is as below,

EXM-The value Document payee bank account number is required. (EXM--1)

EXM-The value Document payee bank account number is required.

Cause The message, EXM-The value Document payee bank account number is required., can not be accessed.

Action Report this problem to an administrator.

My requirement is to update this error to a more meaningful error.
