Errors are messages that indicate serious problems which the user must acknowledge in order to continue processing.

(OMS-75018) Error messages show a graphic depiction of an alarm bell, the message text, and the "OK" button.

Examples:

"Please enter a unique Territory Code."

"Field must be entered."

"You cannot delete this Customer because it is referenced on an Order."

"You do not have sufficient authority to approve this Order."

(OMS-75034) Standard Forms function keys pressed at inappropriate times, where no explanation is necessary, should merely beep.
