| Cross-docking time windowCross-dock order lines that must be generated must be for
inbound order lines that have a planned receipt date that tallies with the
planned delivery date of the outbound order line, taking into account the cross-dock lead time that lies between these two dates.
If the cross-dock lead-time is subtracted from the planned delivery date of the
outbound order line, the result is the planned receipt date of inbound order
lines that can be considered for linking to a cross-dock order. Being expressed in seconds, an inbound order line's planned
receipt date will never exactly match the planned delivery date of an outbound
order line. Therefore, inbound order lines must be taken into account with a
planned receipt date that is shortly before or after this calculated date. For
this purpose, you can specify minimum and maximum time tolerances in the Generate Cross-dock Orders and Cross-dock Order Lines (whinh6200m000) session, which
creates a time window for the planned receipt date. As a
result, all inbound order lines that have a planned receipt date that is within
this time window are taken into account for cross-dock order line
creation. If you set both the minimum and maximum time tolerances to zero, LN ignores the time
window. Example The following figure shows lead-time calculation without a time
window. Explanation - The cross-dock lead time is planned backward from the planned
delivery date of the cross-dock order (= outbound order line) to obtain the
calculated planned receipt date.
- The inbound order line that is received on this date/time (only
one) is taken into account for creation of cross-dock order lines.
Example The following figure shows lead-time calculation with a time
window. Explanation - The vertical line to the left of the calculated planned receipt
date indicates the minimum time tolerance, while the vertical line to the right
of the calculated planned receipt date indicates the maximum time
tolerance.

In this case, other inbound order lines are taken into
account as well for creation of cross-dock order lines. Some goods might be
received before the calculated receipt date, others after the calculated
receipt date: - Goods that will be received earlier can be cross-docked and
shipped earlier, or will have to wait at the receiving or staging location to
be shipped on the planned delivery date.
- Goods that will be received after the calculated receipt
date, but within the time window, will also be cross-docked for this cross-dock
order. These goods are already too late for shipment, but still cross-docking
is faster than in-bounding and out-bounding the goods.
- Inbound order lines with a planned receipt date that falls
outside the time window will not be taken into account for this cross-dock
order, but might be taken into account for another cross-dock order. This other
cross-dock order is for another outbound order line that might have another
planned delivery date. This results in another calculated planned receipt date
and a shifted time window.
The order in which inbound order lines are linked to a
cross-dock order is as follows: Inbound order lines that were already received. The time window is not taken into account. Remaining inbound order lines. These lines are linked according to their planned receipt
dates. Inbound order lines with the earliest planned receipt dates will be
linked first. Here, the time window is taken into account.
Note - Your line of business determines how time tolerances are set.
Best results will be achieved by trial and error.
- Time tolerances can be expressed in hours or days.
