Production IDs and Production Schedules Using PeopleSoft Manufacturing

Creating Production IDs

You can use the Production ID Maintenance component to add or maintain a production ID one at a time. When you manually add a production ID, determine whether production is forward or backward scheduled. The selection is based on whether you know when you want to start production or when the item is due:

If the production ID is based on the completion date and time, or due date and time, it is backward scheduled, and the system calculates the actual start date and time.
If the production ID is based on the start date, it is forward scheduled, and the system determines when the assemblies will be completed.

Automatic calculation of the opposing date and time applies only if you specify a routing for the production ID. In addition, the system calculates 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.

If a production ID is added in the Firmed or Released status, the actual start dates and times and due dates and times for each operation in the manufacturing process are also calculated.

You can also add or maintain production ID information one week at a time using the Production by Area pages. This gives you a one-week view of all production taking place in a selected production area. By navigating to the details by day, you can view daily production ID and production schedule information. When adding production IDs, you select the date on which production will be completed and the system automatically backward schedules the production ID to determine the start date of production.

Creating Production Schedules

Production schedules are always entered with a quantity due for a day of the week, and the system determines the production start date and production start shift using backward scheduling.

Note:

Because production schedules are always backward scheduled, you enter the production end quantity, and the system calculates the required production start quantity.

When you manually add a production schedule in the Entered status, the system:

Determines the production start date and shift when the production due date and shift are entered.
Determines the actual start date and time as well as the actual due date and time for the production start date and shift and production due date and shift, respectively.

When you add a schedule in the Firmed status or release a production schedule, the system must:

Calculate an actual start date and time or due date and time.
Calculate actual start dates and times and due dates and times for each operation in the manufacturing process.

Calculating Start and Due Dates for Production IDs and Production Schedules in PeopleSoft Manufacturing

PeopleSoft Manufacturing calculates start and due dates based on the production item's routing, and does not include other production that uses the required work centers or resources. If capacity and material availability are concerns, manually add a production ID or production schedule using PeopleSoft Manufacturing. When you add the production, estimate start and due dates and then schedule the actual start and due dates for the production ID or production schedule using PeopleSoft Supply Planning.

If you are using PeopleSoft Manufacturing to schedule production, there are several factors that affect the actual start date and time and actual due date and time of each operation in addition to the planning lead times:

Operation overlap, based on a percentage or send-ahead quantity.
Setup that can occur during queue time (or at any time once production begins).
Setup time that is included in scheduling the operation.
Operation intensity.
Work center calendar, if one exists.
Production calendar, if one exists.
Five-day work week calendar.
Operation yield.

Define these factors when you set up manufacturing data for each business unit, item, work center, or routing. Once the system creates the operation list for the production ID or production schedule, it reschedules each operation any time that the operation list is modified.
