Order Quantity Fields

Increases or decreases to the originally requested quantity are common types of changes made to demand lines.

Increasing Requested Quantity

For material stock requests, you can increase the requested quantity only if the demand line is not in the releasable state, reserved, promised, or if no backorders exist. After reservation processing, you can increase order quantity by creating a new schedule or demand line for the order.

Note:

In some cases, reducing the quantity cancels backorders. Under these circumstances, you cannot increase the quantity after it is reduced even though the demand line is not in the releasable state. If you cancel backorders in response to a quantity reduction, you cannot change the Cancel Backorder setting, the Ship Partial setting, or the lot allocation.

In the Maintain Stock Requests component, changes to the requested quantity must be entered in the existing ordering unit of measure. You cannot change the unit of measure.

Decreasing Requested Quantity

You can reduce the requested quantity on a material stock request by the quantity that has not been shipped. For example, if the requested quantity for an order is 100 each and 40 each have been shipped; you can reduce the order quantity up to 60 each (the portion of the requested quantity that has not been shipped). The order quantity cannot be reduced to less than 40 each.

When you reduce the quantity for material stock requests, all unpicked demand quantity is automatically canceled. If the full requested reduction cannot be satisfied, a warning appears indicating the quantity that was canceled. To account for the remaining portion of the reduction quantity, you can underpick or short ship the order in PeopleSoft Inventory.

Note:

Underpicking and short shipping do not change the quantity requested. Before shipping an underpicked or short-shipped line, confirm that a demand line has a backorder rule defined to cancel backorders or the Cancel Backorder check box is Yes so that backorders are not created at shipment. You can change the backorder settings for material stock requests and sales orders associated with a pick batch ID in the Maintain Stock Requests component.

Depending on the amount of the reduction and the backorder settings, when you decrease the quantity for an order, the system determines whether to cancel existing backorders, create canceled backorders, or deallocate existing allocations. You cannot directly reduce backorder quantity; it is decreased only as a result of a quantity decrease for a demand line.

In the Maintain Stock Requests components, you must enter changes to the requested quantity in the existing ordering unit of measure. You cannot change the unit of measure.

Decreasing Requested Quantity for Promised Demand Lines

When you decrease the requested quantity for a demand line that has been fully promised, the promised quantity for the demand line is also decreased. When you decrease the quantity for a demand line that has been partially promised and allows backorders, the unpromised part of the demand line quantity is decreased first on the associated backorder; any remainder of the total decrease quantity is then subtracted from the promised quantity. If backorders are not allowed (by the backorder rule or Cancel Backorder check box is yes) for the partially promised order line, then unpromised quantities do not exist. In this case, the decrease in quantity is added to the backorder quantity and a canceled backorder with this quantity is created. The promised quantity is also decreased as necessary.

For example, suppose the original demand line quantity is 10 each and 7 each were promised. The demand line's backorder rule was set to cancel backorders, so unpromised quantity does not exist. If you decrease the demand line to 8 each, the backorder quantity is set to 2 each and a canceled backorder with requested quantity of 2 each is created, regardless of the definition in the backorder rule. The promised quantity is updated because it is less than the difference between the original order quantity (10 each) and the backordered quantity (2 each). If you decrease the order quantity to 5 each, however, the system also decreases the promised quantity to 5 each because the original promised quantity of 7 each is greater than the difference between the original quantity (10 each) and the backorder quantity. In this case, the backorder quantity of the demand line is set to 5 each and a canceled backorder for 5 each is created.
