Planned orders are generated by MRP and are replanned as requirements change. You cannot record inventory transactions or labor feedback against them, or change quantities, dates, bills of material, or routings.
Approving a planned work order with Planned Work Order Approval (23.10) changes its status to firm planned.
See Material Requirements Planning for more information about planned orders.
Note: Work orders with statuses other than Planned have fixed quantities and due dates and are therefore not replanned by MRP.
