CUM management
CUM management allows customers to track demand fulfillment from schedule to schedule to accommodate out of order shipping and receiving. The robust CUM Management system tracks order CUMs as well as Fabrication and Material CUMs. Manual adjustments are supported as well as model year change-over. Integrated reporting tools create high visibility of ahead/behind CUM quantities. Combined with the alerting system, CUM events are tracked on the EMC as well as through automated alert notification.
Mid-Year Startup
After turning on CUMs, the first schedule sent is used to set both the CUM Required (the CUM Required before the first requirement of the schedule) and CUM Shipped quantities. Both quantities are set to match the field selected as the CUM Basis in the customer characteristics.
CUM Required
CUM Required is the total quantity due to date. Because CUM Required is date specific, it is variable based on the current date and requirement dates. Each time a schedule is sent (imported), the prior CUM Required is updated to match the field selected as the CUM Basis in the customer characteristics. This quantity indicates the total quantity due before the first requirement.
If using a CUM-to-Net strategy, each requirement quantity is a CUM Required for the requirement date. The net quantity for the first requirement in the schedule is calculated as the difference between the prior CUM Required and the requirement quantity. Subsequent net requirements are calculated as the difference between the requirement quantity and the previous requirement quantity.
If using a Net-to-CUM strategy, each requirement quantity is a net due for the requirement date. CUM Required is continuously calculated based on the prior CUM Required and each net requirement.
CUM Shipped
CUM Shipped can either be calculated by the application or set by the customer on each schedule based on the CUM Shipped (YTD) Owner setting in the customer characteristics.
If the CUM Shipped Owner is set to Supplier-Internal, CUM Shipped is tracked by the application based on ASNs and CUM Shipped Adjustments. After the initial CUM startup, the customer no longer controls CUM Shipped. CUM Shipped quantities included on schedules are ignored.
If the CUM Shipped Owner is set to Customer-External, CUM Shipped quantities included on schedules override the application's CUM Shipped. CUM Shipped is then tracked by the application based on ASNs and CUM Shipped Adjustments until the next schedule is sent (imported). At that time, the CUM Shipped is overridden based on the CUM Shipped on the schedule.
