Finding is always easier! That's why I originally stated that I'm interested in your solutions.Christian,
Without dissecting the many points of your post, I can say that I fully understand them all and can confidently say I likely have an existing solution so far as manually updating the necessary data points you're looking for. It's not "automatic" at this time simply because live data links to machinery are not yet available, as far as I'm aware. Of course it runs using FileMaker and the current form factor is basically a single (non-scrolling) screen layout of all the mixes of unit of measure, can be used via touch screen by operators if need be, and may be vastly customized. Apparently, its form is one you may not have been exposed to by any other solution.
So, would you be happier to "find" this or "build" this?
Let me know.
