How do you keep a product from showing up on your purchasing projections without making that product inactive?
You would want to make this product have a status of Non-Stock which will keep it from projecting unless a customer orders it. Additionally, you can give this product a min/max purchase quantity of 0 and set a max expiration date so you can review this item at a later date to determine if you would like to keep it as an active product with a zero max.
