How Supply Is Considered in the Lead Time Based Mode

In the lead time based mode, the planned date is delayed from the requested date based on the lead time defined in the rule being applied.

Settings That Affect the Lead Time Based Mode

• Type of lead time. It can be the total lead time, the cumulative manufacturing lead time, the cumulative total lead time, or a user-defined lead time.

• Type of requested date. If the request type specified by the customer was Shipment, then the requested date is the requested ship date. If the request type specified by the customer was Arrival, then the requested date is the requested arrival date.

How Supply Is Considered

If the requested date is a ship date, then the backlog planning process applies the lead time offset defined in the backlog planning rule and plans using the requested date plus lead time offset after inflating the calendar date to account for any holidays. The process doesn't check whether there is availability of the item because even if there is availability of the item, the availability must be ignored.

If the requested date is an arrival date, the backlog planning process first derives the requested ship date by applying a transit time offset to determine the requested ship date. To determine the offset, the default carrier, shipping mode, and service level associated between the ship-from date and the ship-to date is considered. To derive the planned ship date, the process then applies the lead time defined in the backlog planning rule to the derived requested ship date. Then to calculate the planned arrival date, the process applies the transit time for the specified or default ship method. When determining dates, the process accounts for any calendar constraints.

The planned date is offset from the requested date based on the lead time defined in the backlog planning rule.
