Reservation Lead Days

Reservation lead days represent the number of days required to reserve, pick, pack, and ship the majority of the items in the business unit. The value defined for the business unit (on the Setup Fulfillment-Reservation page) becomes the default for the item level; you can override it. The reservation lead days entered on the Setup Item Fulfillment page represent the number of days required to reserve, pick, pack, and ship a particular item.

The reservation lead days are used by the reservation processes to:

  • Reserve demand lines.

    The requested quantities for soft-reserve items can be reserved when the scheduled shipment date falls within the reservation lead days window defined for the item or business unit.

  • Promise demand lines.

    The requested quantities for ATP items can be fully or partially promised when the scheduled shipment date falls within the reservation lead days window defined for the item or business unit.

Note:

Reservation processing can reserve or promise stock to a demand line. The decision to move the line from the unfulfilled state to the releasable state is made during reservation processing based on the reservation and backorder rules, not the lead days.

You can use the Update Unreserved Orders page or the Shortage Workbench to view orders that are not within the reservation lead days.

The reservation lead days can be overridden on the reservation request if the Allow Override of Lead Days check box is selected on the Setup Fulfillment-Reservation page. In addition, to prevent entry errors, the override value cannot create a scheduled shipment date that exceeds the current date plus the max lead days entered on the Setup Fulfillment-Reservation page. The override value is never used for ATP processing. ATP always uses the reservation lead days at the business unit or item level.

Note:

When the business unit requires closure-calendar validation and processing for receiving activities as defined on the Closure Calendar page, and when the calculated schedule shipment date for the requisition falls on a closure date, the system selects the first valid future date for the schedule shipment date. Therefore, the reservation lead days include only open business days.
