Thank you for your feedback. I do not think MTO is the way to go.
I simply want our stock to be refiled based on the re-order rule. In my mind the stock should be used up via a salesorder.

If you want to replenish your stock so you will use reordering rules and Odoo will generate draft PO when the product’s forecasted stock falls below the set minimum quantity.

Thank you again for your feedback. I thought that reordering rules would indeed trigger an RFQ/PO when it drops below the minimum value. However the salesorder appears to demand the items from the warehouse stock location. Not from the article specific location. I do not understand why.

the sales order appears to demand the items from the warehouse stock location because of the source warehouse in Delivery order operation is the warehouse stock location.

Thank you for your awnser. I have added a picture to my question. I hope you can read it.
It shows the diagram of my Buy route on an specific item. In the far right you can see my re-order rule. When i look at this, i think that, upon a sale, Odoo does nothing with the re-order rule. It will look in the warehouse stock. I could adjust the buy route. But then i would have to make it unique per item.
So i am guessing i do not understand the principle. I simply want an item to arrive into a certain location. and upon sales be picked/sold/replenished on that same location. This should however be item unique. (our warehouse is not one big pile of stuff).

So the question remains, what am i doing wrong?

Thank you for your feedback. I have added some data in hope to clarify my question.
My re-ordering rule already has a trigger which is set to auto. My route is Buy.
Maybe i am missing something in here, but i thought this is all you need to do. (that and assign a supplier to the specific article and make it stock holding)

Thanks again for your feedback. I am only using the "buy" route. Does that mean i have to make an unique route for every article? (we have almost 10000) i thought that was controlled via the reordering rules?

My reference was to the delivery route which is triggered by sale order. If you store the product in LocA the delivery order needs to pull from this location and in the absence of stock at this location your reorder rule is configured to trigger a RFQ.

From what you describe, the reorder rule is triggered from WH/Stock location makes for the suspension that delivery order is looking for the product availability at WH/Stock location rather than LocA.

Am not certain I understand your question on the number of products.. reorder rules are defined at product level as min max and multiples of qty vary by the product.

Delivery route can be on product or product category or sale order line or WH

Hope I have been able to address your question, else it might help if you describe the expected process.

Thank you for your feedback. I have come up with this.
