I'm swamped this week so I'm falling back on an oldie but a goodie. A surprising number of long time users still don't use this so I'll cover here. What is it? Show required fields on a form in RED.
In Great Plains select Tools>Setup>User Preferences or in some versions, Setup>User Preferences, or pick the User Preferences Icon from the shortcut bar.
Select Display. On the right under Required Fields, set Font Color to Red and Font Style to Bold. Click OK and you're done.
Required fields throughout the system now show as Bold Red.
