Make To Stock products are configured as follows:

(Make them stockable products. The important thing to do is make sure Make To Order is UNCHECKED)

You MUST add a Reordering Rule to tell Odoo what the acceptable minumum and maximum level of stock is. It can be 0, but you must have a rule.

You MUST add a Vendor.

After creating your Manufacturing Order, and running the Inventory Scheduler, Odoo will look at:

• the quantity in stock

• the Reordering Rule

• the quantity already on order from confirmed Purchase Orders

• what is needed for the Manufacturing Order

It will raise a Request for Quotation to make sure there is enough on order to complete the order and top up stock levels.

Example 1:

Stock Level: 5 units

Reordering Rule: 0 minimum and 0 maximum

Manufacturing Order: 10 neeeded

Existing Order placed: 0 units

Odoo will suggest an order of 0 + 5 units - 0 units

Example 2:

Stock Level: 0 units

Reordering rule: 100 minimum 500 maximum

Manufacturing Order: 10 needed

Existing Order placed: 0 units

Odoo will suggest an order of 500 units + 10 units - 0 units

Example 3:

Stock Level: 100 units

Reordering rule: 100 minimum 500 maximum

Manufacturing Order: 10 needed

Existing Order placed: 200 units

Odoo will not suggest an order. There are 90 + 200 units expected in stock after the Manufacturing Order is completed.

Note: Odoo has a concept of Forecasted Quantity that it manages to work all of this out - It is defined as the Quantity on Hand - Future Delivery Orders + Future incoming shipments + Future manufactured units (as applicable).
