Expedited lead time

Specify a shorter lead time value for situations that require expedited processing. The Planner always uses the standard lead times on the first pull-planning run. If the first run fails to plan to a date because of insufficient capacity, inventory, or time, the second and/or third planning runs will use expedited lead times (if specified). There are two ways to specify expedited lead time:

  • as a global reduction to the standard lead times
  • as an item-specific, alternate set of fixed and variable lead time values.

Specify the global lead-time reduction value for fixed lead time in ALTPLAN.FEXPLTIME. Specify the global reduction value for variable lead time in ALTPLAN.VEXPLTIME. The Planner applies these values only if the ALTPLAN.SSFLAGS field sets the Use Expedited Lead Time flag AND the expedited lead time value(s) for the item in the MATL table are blank. In this case, the Planner reduces the standard FLEADTIME by the value in FEXPLTIME and/or the standard VLEADTIME by the value in VEXPLTIME (to a lead time value 0 or higher).

For example, consider these values:

  • ALTPLAN.SSFLAGS: Any integer value that sets bit5 (enable global expedited lead times).
  • MATL.FLAGS: Any integer value that turns off bit9 (disable item-level expedited lead times).
  • ORDER.ORDSIZE: 100
  • MATL.FLEADTIME: 48
  • MATL.VLEADTIME: 4
  • ALTPLAN.FEXPLTIME: 2
  • ALTPLAN.VEXPLTIME: 1

The calculation is performed like this: 48 − 2 + (100 * (4 − 1)) = 346 hours

Specify item-specific expedited fixed lead time in MATL.FEXPLTIME. Specify expedited variable lead time in MATL.VEXPLTIME. The Planner applies these values only if the MATL.FLAGS field for the item sets the Use Expedited Lead Time flag. In this case, the Planner uses the expedited lead time values in place of the standard lead time values.

For example, consider these values:

  • MATL.FLAGS: Any integer value that sets bit9.
  • ORDER.ORDSIZE: 100
  • MATL.FLEADTIME: 48
  • MATL.VLEADTIME: 4
  • MATL.FEXPLTIME: 12
  • MATL.VEXPLTIME: 2

This calculation is performed: 12 + (100 * 2) = 212 hours
