ATP Lead Days

ATP lead days represent the number of days that the majority of the items in the business unit can be fully promised for shipment. The business unit value (defined on the on the Setup Fulfillment-Reservation page) becomes the default for a particular item on the Setup Item Fulfillment page. You can override this default.

ATP lead days should be greater than the reservation lead days. If the scheduled shipment date falls within the ATP lead days, the ATP function promises only the full quantity requested. If the scheduled shipment date falls within the reservation lead days, the system promises either the full or partial quantity requested.

Note:

If the business unit requires closure-calendar validation and processing for shipping activities as defined on the Closure Calendar page, and if the number of ATP lead days includes closure dates, the system adds one day for every closed day to the number of reservation lead days to compare against the scheduled ship date. Therefore, the lead days include only open business days.
