You can create discrete jobs in the following ways:
Manually (both standard and non-standard discrete jobs). See: Defining Discrete Jobs Manually.
Manually from a simulation (standard discrete jobs only). See: Simulating and Saving Simulated Jobs.
Automatically using Oracle planning products to plan your standard discrete production, then using the Planner Workbench to implement your planned orders. See: Planned Discrete Jobs.
Automatically using Advanced Planning and Scheduling's High Level Scheduling Engine to schedule jobs and import them into Work in Process
Automatically (standard discrete jobs only) from final assembly orders for specific customer configurations and/or standard assemble-to-order (ATO)/configure-to-order items. See: Final Assembly Orders.
Using the Work Order Interface to import planned orders and updated planned order recommendations. See: Work Order Interface, Oracle Integration Repository, irep.oracle.com
Note: If you have Oracle Shop Floor Management installed, you can create lot based jobs. The entire quantity of a lot based job moves on the basis of the network routing.
You can create planned orders and reschedule recommendations using the Planner Workbench in Oracle planning products. You can modify the due dates and quantities of planned orders, and also firm plan these orders. You can create new discrete jobs by implementing all or some planned orders.
When you create jobs using the Planner Workbench, you can specify the WIP accounting class. Accounting classes can be defaulted. See: WIP Accounting Class Defaults, Product Line Accounting Setup, Discrete Parameters, and Discrete Accounting Classes.
If the job being created is for a lot controlled assembly, the WIP Default Lot Number Type parameter is used to determine whether lot numbers are assigned based on the job name or based on the Oracle Inventory lot number rules.
Discrete jobs created from planned orders use the planned order quantity as the default job quantity. The primary bill of materials and primary routings for the assemblies are used to create work in process bills and routings. Jobs created from planned orders are backward scheduled from the required completion date. The calculated start date is used to determine the bill and routing revisions and revision dates.
Planning takes shrinkage rate, component yield, and safety stock into consideration in the planning process. Once you define the standard job, supply is calculated using the following formula:
available supply quantity = (MRP net quantity - quantity completed - quantity scrapped) x 1 - item shrinkage rate)
You can also use the Planner Workbench to reschedule existing jobs. For example, you can reschedule every assembly in the plan or you can reschedule only certain specific assemblies.
When you implement planned orders and create discrete jobs, Planning does not take into account the WIP:View Only Released ECOs profile option in the Personal Profile Values window.
Oracle Advanced Planning provides a profile option enabling you to align Work in Process production with engineering changes for planning See: Aligning Engineering Change Order Dates in Planning and Production
You can automatically create final assembly orders for Assemble to Order (ATO) items entered in Oracle Order Management. These discrete job orders are created on a single job to single sales order delivery basis.
On the Sales Order window (which you open from the Discrete Jobs window in Work in Process), you also can associate discrete jobs for both standard items and ATO items with sales orders and thereby allocate production to specific customers.
To determine the job start date, you schedule jobs created from final assembly orders backwards from the order due date. The calculated start date is used to determine the bill and routing revisions and revision dates.
