Partial Backorder

A supplier may not be able to deliver the ordered quantity on a purchase order line on the date requested and may deliver the quantity across different dates. In such cases, the order line acknowledgment indicates a partial backorder.

There are different ways in which a partial backorder is communicated in a purchase order acknowledgment.

If there is only a single acknowledgment for the line, then the acknowledgment code value in the acknowledgment may be a partial backorder code or a backorder code.
- Option 1: A partial backorder code is used to communicate a partial backorder. The partially backordered quantity is the difference between the line quantity and the quantity in the acknowledgment. The quantity in the acknowledgment is processed as the accepted quantity.
- Option 2: A backorder code is used to communicate a partial backorder. The quantity in the acknowledgment is the partially backordered quantity. The accepted quantity is the difference between the line quantity and the quantity in the acknowledgment.
- Option 3: A partial backorder can be communicated using two acknowledgments for a line. While one acknowledgment indicates the partially backordered quantity (with a backorder code), the other acknowledgment indicates the accepted quantity (with an accept code).
- Option 4: A partial backorder can be communicated using two acknowledgments for a line. While one acknowledgment indicates the partially backordered quantity (with a backorder code), the other acknowledgment indicates the accepted quantity (with a partial backorder code).

Single Acknowledgment with a Partial Backorder Code

A single acknowledgment for the line with an acknowledgment code value is present in the schedulePartialBackOrder code list. The acknowledgment must also contain the OrderQuantity and one of the date fields (PromisedDate, PromisedShipDate, PromisedDeliveryDate).

The data for a single acknowledgment with a partial backorder code option is mapped in this table.

One Acknowledgment with a Backorder Code and Another Acknowledgment with an Accept Code

There are two acknowledgments present for the line, one with an acknowledgment code value in the scheduleBackOrderChange code list and the other with an acknowledgment code value in the lineAccept or scheduleAccept code lists. The OrderQuantity on the purchase order line is computed by adding the OrderQuantities from the two acknowledgments.
