Purpose

This process describes how the system determines deviations between the planned deliveries and the projected deliveries of a work order, if you are using the permissible class DA_QTY_TIME_02 for the assignment algorithm. The system performs deviation analysis separately for the transportation phase inputs (shipping date/time, quantity) and for the transportation phase outputs (delivery date/time, quantity). Thus the system treats the shipping at the ship-from location differently than the receipt at the customer location. However, because the procedure for transportation phase inputs and transportation phase outputs is the same, this section uses the superordinate term "transportation PIO".

To determine deviations, the system assigns projected transportation PIOs to the planned transportation PIOs. The system compares the quantity and the date/time of a planned transportation PIO with the quantities and dates/times of the associated projected transportation PIOs. In the case of deviations, the system creates corresponding alerts, required actions, and statuses for the planned transportation PIO.

The process likewise applies for determining deviations between plan PIOs and actual PIOs.

Process

The system assigns, to every planned transportation PIO, the projected transportation PIO that chronologically matches only this single planned transportation PIO. These are the projected transportation PIOs that comply with this planned transportation PIO within the time tolerance, but with no other planned transportation PIO.

The system processes the projected transportation PIOs that chronologically match multiple planned transportation PIOs. If a projected transportation PIO chronologically matches more than one planned transportation PIO, the system assigns the quantity of the projected transportation PIO as follows to the planned transportation PIOs:

Das ...

The system first fills the earliest transportation PIO up to the minimum quantity (planned quantity minus underdelivery tolerance), then fills the next planned transportation PIO up to the minimum quantity, and so on.

If the quantity of the projected transportation PIO is not yet consumed at this point, the system fills the planned transportation PIOs to the exact planned quantity, starting again with the earliest planned transportation PIO.

If the quantity of the projected transportation PIO is still not consumed by this point, the system fills the planned transportation PIO to the maximum quantity (planned quantity plus overdelivery tolerance).

If the quantity of the projected transportation PIO is still not consumed by this point, the system assigns the scrap quantity to the next planned transportation PIO.

The system processes the projected transportation PIOs that do not match any planned transportation PIOs within the time tolerance. The system assigns such a projected transportation PIO to the next planned transportation PIO.

The system compares the quantity and the date/time of a planned transportation PIO with the quantities and dates/times of the assigned projected transportation PIOs. Depending on the results, the system sets a combination of statuses for quantity violations and date/time violations, according to the following situations:

High - on time

Low - early

High- late

Low - on time

Low - late

Low - early

Correct quantity - early

Correct quantity - late

Example

The following graphic displays the planned transportation PIOs 1, 2, and 3 and the projected transportation PIOs A, B, and C. The quantity tolerance and time tolerances for the planned transportation PIOs are depicted as a square.

In the following graphic, you can see how the system assigns quantities from the projected transportation PIOs to the planned transportation PIOs. The partial quantities from the projected PIOs are "stacked" under the respective required quantity of the transportation PIO.Here you can compare the requested quantity for a planned transportation PIO with the total assigned quantity from the projected transportation PIOs.

Results of the assignment:

The planned transportation PIO 1 can be delivered on time within the time tolerances, with two partial deliveries containing the exact quantity required. There is no alert or status for quantity violations or date/time violations.

For the planned transportation PIOs 2 and 3, there is no projected transportation PIO available within the time tolerance. The system assigns the projected transportation PIO C completely to the chronologically-closer planned transportation PIO 3. As a result, the planned transportation PIO 3 is covered too early and with a surplus quantity. The planned transportation PIO 2 remains uncovered. The system creates corresponding alerts and statuses.
