orders become either purchase requisitions, firm-planned work orders, or
are added to the item’s production line schedule.
Approving a planned purchase order deletes the planned order and creates
a purchase requisition, which can be filled by a purchase order.
Approving a planned work order changes its status to firm planned. MRP
does not replan firm planned orders, but instead, generates action
messages as needed. A firm planned order has a work order bill and a
routing with scheduled operations. These are not fixed. Bills are reexploded
by MRP, while routings are re-exploded by CRP. Both are reexploded
when the status is changed to Exploded, Allocated, or Released.
Approving a planned line order adds the order amount to the schedule for
that item’s production line. The production schedule sequence for a given
line can be viewed and modified using Line Schedule Workbench. Once a
production line’s schedule is established, run Repetitive Schedule Update
(18.1.18 or 18.22.1.18) to remove the planned line order from MRP.
After a planned order is approved, MRP does not change the quantity or
due date on the order the next time it is run. Instead, it generates action
messages suggesting changes to the order. You can modify firm planned
order due dates and quantities as needed in Work Order Maintenance
(16.1), Purchase Requisition Maintenance (5.1.4), and Line Schedule
Workbench (18.1.10 or 18.22.1.10).
