Defining Production Scheduling Methods

You define a production scheduling method when you create a new production ID. When you manually add a production ID, the system schedules it based on whether you know when you want to start production or when the item is due:

• If you decide to schedule the production ID based on the completion date and time or the due date and time, it is backward scheduled.

  In this case, the system calculates the actual start date and time. The production start date and shift as well as the production due date and shift associated with both the actual start date and time and due date and time are determined.

• If you decide to schedule the production ID based on the actual start date and time, it is forward scheduled.

  In this case, the system determines when the assemblies will be complete and calculates an actual due date and time. The production start date and shift as well as the production due date and shift associated with both the actual start date and time and due date and time are determined.

PeopleSoft Manufacturing always backward schedules production schedules. When adding a new production schedule, you enter a production due date and production due shift for the production quantity. The system then calculates the production start date and production start shift. The actual start date and time as well as the actual due date and time are also calculated.

When changing the status for a production ID or production schedule to Firmed or Released, the system copies the item's routing and creates an operation list. As the system creates the operation list, it also determines the actual start date and time and actual due date and time for each operation. When the system creates the operations list, it reschedules each operation any time that it's modified.
