I want to manually click a button (or checkbox) to add a single stock item to a quote request table. I prefer this manual method over the automation of formulating the difference between current and minimum inventory fields. I hope I don't have to create a many-to-many relationship.
Can you describe your current set up as of now? Do you currently have "Line Items" that are child records to your quote? Is the Item you are adding always the same? or do you need to be able to change that Item (without changing the formula)?
