Creating Component Lists for Regular Production

To create a component list for regular production, the system copies the item's BOM. The component list defines the required components for the production quantity. You define which BOM to use for production by selecting the appropriate revision of the BOM or using the BOM in effect at the time production is due.

Note:

Components that are supplied by an outside supplier aren't included when creating the component list. These components are marked as subcontractor-supplied on the item's BOM.

Note:

Floor stock and expensed items are included on the component list for informational purposes only. Although the system calculates and displays a scheduled quantity, these items aren't included in any pick plan and therefore won't be issued to production during the material release process.

When creating the component list, the system determines the scheduled quantities and current scheduled quantities for each of the end item's components. Scheduled quantity is based on this formula:

[(operation start quantity x quantity per assembly) / component yield]

The scheduled quantity is calculated based on the quantity of the end item started at the operation where the component is used. In addition, the system also initializes the components operation sequence and quantity per assembly or per order with information from the BOM. The components issue method defined for the end item within the production area is also defined at this time.

If you're adding a new component, the scheduled quantity is calculated the same as when a production ID is created (operation start qty * qty per assy)/component yield.

If you're changing the scheduled quantity, then the system calculates the quantity per assembly: QPA = (current component scheduled qty * component yield) /operation start qty. The operation start quantity factors in any planned yield loss or actual scrap that has occurred at prior operation sequences.

If you're changing the QPA, then the current scheduled quantity is recalculated using the operation start quantity at the operation sequence where the component is required.
