his field applies to APS.
Enter the fixed expedited lead time (in days) for this item. When you run the APS Planning activity, if the initial pull-planning pass using standard lead time projects a date in the past, the Expedited Fixed Lead Time will be used.
Keep in mind that the Expedited lead time values on the Items form replace the standard lead time values, while the Expedited lead time reduction fields on the Planning Parameters form REDUCE the standard lead time values. This item-level value overrides the global reduction value if both are specified.
The system applies this value only if the appropriate Use Expedited Lead Time parameter (For Planning and/or For ATP/CTP) is enabled.
See Defining Lead Time for more information.
On the Material Constraint form, the fixed expedited lead time is displayed for the item.
