Prevent past date entry on the delivery date field

Hi Guys,

I was wondering whether it is possible within standard SAP Business one 8.8 to prevent users from entering past date in the delivery date field on the Sales order screen. I have people making mistakes by entering 10/10/2010 instead of 10/10/2011. This caused problems with reports etc..

Is there a formatted search query i can create to warn/alert users with a message stating incorrect date entered? Please advice best course of action?

Regards
