I have a BoM to produce 100 units.

It takes 8 minutes to produce those 100 units.

For an order of 10,000 units, I expect it to take 8,000 minutes.

However, if I set the BoM > Operation > Expected Duration = 08:00. Then, Odoo gives me a work order for 80,000 minutes.

Note: the Work Center Capacity is set to 1.

I'm on Odoo 17. 

Also, please link to documentation... I could not find it.
