Customer would like to restrict some user from answering YES to this warning. I have looked in role maintenance and even in customizer to try to disable the YES key...cannot find it. Any ideas from anyone???

If there was a security event / module option for this, the normal coding practice is to show a message box with a single OK button (which implies a NO answer). However in the code it appears like whether it be a Rcpt of Goods, Rcpt of Invoice, or Return of Goods, it always shows the Yes and No buttons where it defaults to No.
