Greetings Experts, the forum has been a major help in my developer journey, even though am not an expert yet, am looking forward to being one. I have come up with this code that should control\avoid input of duplicate Delivery Note Number during the sales entry input. I need help in the below areas - 1. when using $$NumItems function to control the Delivery note Field, I can still use a duplicate delivery note number. 2. On the Delivery notes Report, when I drill in to the Voucher, it has no information. Assistance will be highly appreciated
