It’s hard to give a concise answer not knowing exactly what “notify me” actually means. For example, are you looking for a constant monitoring of these items and when one gets low something pops up to notify? Or do you want a screen to look at whenever you want which shows you any of the items with a low inventory? Or maybe something else.
I can easily see a screen (Form) to call up when wanted. In creating the DB let’s say you have an inventory record which has a current inventory
field and a low
indicator field. Using a query, the screen (Form) would display all items where the current is less (or equal if wanted) than the indicator field.
For the constant monitoring it could be much more difficult. You don’t want the Base file using up all resources so a triggering event needs to be established. This certainly will require coding at a minimum.
