Task Generation
You can go to the Settings page and select the menu: Task Generation.
For the Inventory you can generate a Task if the current stock drops below the desired stock.
The generated Task will be named like this: Buy "Itemname" for your Inventory.
Tip
A Task will only be created EACH time your current stock drops by -1 and is below the desired stock.
So decreasing your current stock twice and both are below the desired stock will create TWO Task's.
