This feature can help you improve your sales department's performance and your inventory management by using your sales forecast to purchase products by only generating a PO or a SO.
Future Sales from a PO: Instead of starting with a prebook, the future sales process may start with a purchase order, once the products are confirmed by the vendor, they will go right into the Future Inventory.At this point, the sales team can see the products and offer them to the customers (note that the products are not actually in your warehouse).
Future Sales from a SO: Instead of beginning with a PO, this sales process starts with a standing order which then, depending on your SO settings, generates a manual or automatic PO, once the products are confirmed by the vendor, they will go right into the Future Inventory where the sales team can see the products and offer them to customers (note that the products are not actually in your warehouse).
Future Sales from a Prebook: The future sales process may start with a prebook with Future Sales customer. Once the PO is created and approved by the vendor, the products will be deleted from the prebook (see below) and will go to the Future Inventory. At this point, the sales team can see the products and offer them to the customers (note that the products are not actually in your warehouse).
