@Ray. I'm hoping to get your attention on my clarification.

Thanks.

Thanks Ray.

One clarification: Odoo assumes we want to produce 100 chairs - not 110. However, we may consume more parts than in the perfect/ideal manufacturing process. This is what the scaling factor does. Correct?

What if I wanted to increase production of the final product? Would that be a manual intervention? Or can we do that programmatically?

Question about the workflow...

Let's say I produce 100 chairs.

At the leg work center, I scrap 10 legs.
At the seat work center, I scrap 10 seats.
At the back work center, I scrap 10 backs.
The BoM accounted for that, so I picked the right amount of parts.

Let's say the entire MO took 1-week to process. I have to remember (or check the scrap data) to tally the consumed parts and add that to the confirmation step.

Is that right? Or, can Odoo know, based on what I scraped and MO, what I consumed in the operation?

What have you tested yourself? (That's the best way to understand my reply). The quantity field on a Manufacturing Order is editable, meaning you can increase the amount you produce. You can try this and see that we scale up the quantities of each component accordingly. As long as you scrap within the MO (from the Action Menu, SCRAP PRODUCTS) Odoo will include the cost of both the consumed and scrapped components in the calculation of the cost of the finished product(s).

Thanks Ray. Yes, I did test your suggestions.

Grossing up the components assumes that the scrap happens during the MO or that the components themselves are defective.

Our workflow is about the end product... meaning we can't account for the defective project until production is done.

For us then...the answer is a manual intervention. Or, custom dev to gross up the number of end products that needs to be produced.

Thanks.
