Maintaining Master Schedule Orders
You can enter master schedule orders as firm planned work orders or create them using repetitive schedules. Under some circumstances, they are also automatically generated when you create flow scheduled orders.
Work Orders
You can enter master schedule orders as firm planned orders using Master Schedule Order Maintenance (22.13) or Work Order Maintenance (16.1). When you set the order status to Firm Planned, MRP explodes the parent item’s product structure when planning the gross requirements for its components. Master schedule orders are managed and released like normal work orders.
See Work Orders.
Flow Scheduled Orders
When you enter a flow scheduled order using Flow Schedule Maintenance (17.13.3) and do not include a reference to an existing work order, the system automatically creates a type W (Flow) work order for the due date and required quantity entered on the flow scheduled order. The status of the order is set to exploded, and MRP uses it when planning requirements.
See User Guide: QAD Lean Manufacturing.
Note: You cannot update system-maintained type W work orders using Master Schedule Order Maintenance or Work Order Maintenance.
Repetitive Schedules
If you use the Advanced Repetitive or Repetitive module to manage your manufacturing processes rather than the Work Orders module, you can enter your master schedule as a repetitive schedule.
See Advanced Repetitive and Repetitive.
Do this using Schedule Maintenance (18.2.1 or 18.22.2.1). Then, explode the repetitive schedule to create scheduled orders by running Net Change MRP (23.1), Regenerative MRP (23.2), and Schedule Explosion (18.2.4 or 18.22.2.4). Exploding the repetitive schedule creates new scheduled orders and revises existing orders to support the repetitive schedule.
Note: You can modify the master production schedule by modifying the repetitive schedule and then re-exploding it.
Scheduled orders are work orders with a type code of Scheduled and a status of Exploded. They have their own bills of material.
To produce the master scheduled items, you can use the programs in the Advanced Repetitive or Repetitive module or convert the scheduled orders to regular work orders, if required.
Note: When a scheduled order is converted to a regular work order, it is no longer part of the repetitive schedule.
