How to Work: Lock Confirmed Sale Order in Odoo 18 (Enterprise)
In Odoo 18 Enterprise, the Lock Sale Order feature helps prevent accidental or unauthorized changes to a confirmed sales order. Once a sale order is locked, users cannot edit the order lines, quantities, prices or other critical fields. This is especially useful for maintaining data accuracy after confirmation.
