Sorry for the long silence here; too many distractions. These are all good suggestions, but sadly, they don't fix my main problem.
Probably the best way to explain this is, ""I need a GUI on top of these data changes."" The UDT of ""Trucks"" with fields for order number and weight are good. But I need a way to drag n drop the order into a truck for a specific day, showing real time the unused capacity in the truck. Once ""loaded,"" an order can be benched, replaced by a higher priority order. The orders are scheduled out ~5 days. Nothing is final until the evening before the trucks leave in in AM.
I thought this would be functionality I'd be able to find pretty easily, but apparently not. The ad hoc nature of this business need seems unusual, as I haven't something to handle it. Route Sell and others work off of pretty strict rules.
So, if we have to but a custom front end on this, what is the best way to approach it? It would be great to be browser-based, using BOI to communicate to Sage 100, but I might be off base. What do you think?
