Backorder

If the acknowledgment has an acknowledgment code value that's in the scheduleBackOrderChange code list, then the fields that are updated include the Promised Ship Date or the Promised Delivery Date on the PO, or else the descriptive flexfields on the PO header and line are updated. This table displays the data mapping for backorder.

Oracle-1-0-B2B-Purchase-Order-Acknowlegment-In-V2	changePurchaseOrder
`B2BPurchaseOrderAcknowledgment/OrderNumber`	`OrderNumber`
N/A	`SoldToLegalEntityId` This is populated during processing.
`B2BPurchaseOrderAcknowledgment/AcknowledgmentCode` This value needs to be in the `orderAccept` or `orderChange` code list, it's used for processing.
`B2BPurchaseOrderAcknowledgment/AcknowledgmentReason`	`ChangeOrderDescription` If the `AcknowledgmentReason` isn't provided in the payload, then it will be set to Change to the Order.
`B2BPurchaseOrderAcknowledgment/SupplierOrderNumber`	`SupplierOrderNumber`
N/A	`ChangeOrderInitiatingParty` Set to SUPPLIER.
	PurchaseOrderEntryLine
`B2BPurchaseOrderAcknowledgment/Lines/LineNumber`	`LineNumber`
`B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/AcknowledgmentReason`	`ChangeReason` If `AcknowledgmentReason` isn't provided in the payload, then this is set to Not Provided.
`B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/AcknowledgmentCode`	Action If the acknowledgment code value is in the `scheduleBackOrderChange` code list then this is set to CHANGE.
N/A	`PurchaseOrderEntryLine/PurchaseOrderEntrySchedule` Schedule is auto generated.
N/A	`ScheduleNumber` This is autogenerated.
`B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/AcknowledgmentReason`	`ChangeReason` If `AcknowledgmentReason` isn't provided in the payload, then this is set to Not Provided.
`B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/PromisedDeliveryDate` or `B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/PromisedShipDate`	`PromisedDeliveryDate` or `PromisedShipDate` If `PromisedDeliveryDate` is provided and the Buyer Managed Transport isn't selected, the date value is mapped to `PromisedDeliveryDate`. If `PromisedShipDate` is provided and the Buyer Managed Transport is selected, the date value is mapped to `PromisedShipDate`.
`B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/AcknowledgmentCode`	`Action` If the acknowledgment code value is in the `scheduleBackOrderChange` code list then this is set to CHANGE.
	PurchaseOrderEntryLine/LineFlexfield
N/A	`b2bProvidedDateNote` If `PromisedDeliveryDate` is provided and the Buyer Managed Transport checkbox is selected on the PO, then this field is set to Backordered-Promised Delivery Date Provided. If `PromisedShipDate` is provided and the Buyer Managed Transport checkbox isn't selected on the PO, then this field is set to Backordered-Promised Ship Date Provided. If neither `PromisedDeliveryDate` or `PromisedShipDate` are provided then this field is set to Backordered-No Date Provided.
`B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/PromisedDeliveryDate` or `B2BPurchaseOrderAcknowledgment/Lines/Acknowledgments/PromisedShipDate`	`b2bProvidedDate` If `PromisedDeliveryDate` is provided and the Buyer Managed Transport checkbox is selected on the PO, then this field is set to the `PromisedDeliveryDate`. If `PromisedShipDate` is provided and the Buyer Managed Transport checkbox isn't selected on the PO, then this field is set to the `PromisedShipDate`. If no date is provided in `PromisedDeliveryDate` or `PromisedShipDate`, this field is blank.
	HeaderFlexfield
N/A	`b2bAckReviewRequired` If one of the descriptive flexfields is populated, this field is set to One or more lines have acknowledgment comments.
