What GSA (guest relation) should do if Front office manager (her manager) asked to not mention in daily reports mistakes of Front Office?

in polite why she must explain how it positive to show the mistakes as to avoid it in future.

also its one of her job duties to mention all the good and nigative comments .

 for me its very important to write down usual mistakes for as long as its well guided for the betterment of the front office, common mistakes happen and should be reported accordingly.

this is my job I can't do as the manager asked we follow as we are on duty.
