That makes sense. 

Thank you for the quick response.

Reordering rules assume to be generated not based on manufacturing / sale or any other orders. An actual trigger is a reordering rule, which, in a row, does NOT have a link to an exact object. A simplistic example:

1. Stock level is 10 (minimum is 5)

2. You sold 3 in a sale order

3. You consumed 3 in a manufacturing order.

4. Now level is 4. Odoo generates an RFQ to make stock 15.

5. You consumed 4 in a manufacturing order. The level is now 11. No RFQ is created.

6. Which document triggers this procurement? It is hardly possible to reveal, especially if you have multiple orders.

Thus, to reach your goal you either should use make-to-order re-supply methods, or develop some complex algorithms to make this linking based on your company specifics.
