Calculate loading and unloading dates

In the Planned Loads/Shipments (whinh4180m000) session, you can use the Calculate commands to calculate the loading and unloading dates for a planned load or shipment.

Calculate loading dates

If LN determines the loading date and the lead times are expressed in hours, LN takes into account all the time that is available on a day according to the actual calendar. However, if the lead times are expressed in days, LN considers a day as a whole day if the actual calendar indicates that time is available on that day.

Consider the following example, in which the lead times are expressed in hours:

System date/time (= order creation date and time): Wednesday 7:00:00.

Outbound lead time: two hours.

The actual calendar is available from Monday through Friday each week, and has an 8:00:00 start time and an 18:00:00 end time.

According to the actual calendar, a calendar correction must be added: the actual time to which the outbound lead time will be added is Wednesday 8:00:00. So, the loading date is Wednesday 10:00:00.

In the following example, the lead times are expressed in days:

System date/time (= order creation date and time): Wednesday 17:45:00.

Outbound lead time: one day.

The actual calendar is available from Monday through Friday each week, and has an 8:00:00 start time and an 18:00:00 end time.

According to the actual calendar, no calendar correction is added. If, according to the actual calendar, some time is available on a day, the day is considered as a whole day. Consequently, Wednesday is considered a whole day because 15 minutes are left. The loading date is the start time of (in this example) the next day, Thursday 8:00:00.

Calculate unloading dates

The unloading date is calculated as follows:

Unloading date = PDD + TT + CC

PDDPlanned delivery date
TTTransport time
CCCalendar correction (ship-to)

LN does not take into account the transport time if the warehousing order originates from a production order.

If LN determines the unloading date and the lead times are expressed in hours, LN takes into account all the time that is available on a day according to the actual calendar. However, if the lead times are expressed in days, LN considers a day as a whole day if the actual calendar indicates that time is available on that day.

Consider the following example:

Planned delivery date: Wednesday 10:00:00

Transport time: eight hours

The carrier's actual calendar has a 7:00:00 start time and a 17:00:00 end time. The ship-to's actual calendar has an 8:30:00 start time and an 18:00:00 end time. Both actual calendars are available from Monday through Friday each week.

The carrier will carry the goods for seven hours on Wednesday (from 10:00:00 until 17:00:00) and for 1 hour on Thursday (from 7:00:00 till 8:00:00). So, according to the carrier's calendar, the planned receipt date is Thursday 8:00:00. However, if you also take into account the ship-to's actual calendar, the default planned receipt date is Thursday 8:30:00.

Note

This formula is also used to calculate the planned receipt and delivery dates by means of the Calculate Delivery Date and Calculate Receipt Date commands in the Warehousing Orders (whinh2100m000) session. In the Warehousing Orders (whinh2100m000) session, the unloading date is the receipt date and the loading date is the delivery date.

Freight Management

If Freight is implemented, the Freight load building engine uses the route plans, standard routes, and address lead times defined for the loading and unloading addresses to calculate the loading and unloading dates.
