Examiners look much more favorably upon issues that are self-identified and self corrected. Was the error caught through your normal quality assurance processes? If it was, then that demonstrates that your quality assurance processes are working.
To show that your BSA Program is working, also document any follow-up training that was done with the employee who made the error. If this was an isolated occurrence, it most likely would not be a concern during an exam.
