Hi,

In Odoo 17, the ability to click "Produce All" for MO (Manufacturing Order) documents even when there is insufficient inventory is a design choice that stems from the concept of planned production and procurement.

Here are some reasons why this is allowed:

Planned production: Odoo's manufacturing module is designed to support planned production, where production is scheduled in advance based on forecasted demand, material availability, and production capacity. The "Produce All" button allows users to plan and schedule production, even if the required materials are not yet available.

Procurement: When you click "Produce All" with insufficient inventory, Odoo's procurement system is triggered to generate procurement requests for the missing materials. This ensures that the necessary materials are ordered or produced in time to meet the production schedule.

Hope this helps.

Thanks.
