Using XML Messages with an SAP ERP Back-End System

If you, as a customer, use an ERP back-end system as of SAP R/3 4.6C, you can integrate the back-end system with the purchase order collaboration of SAP SNC using XML messages and IDocs, as follows:

Up to enhancement package 3 for SAP ERP 6.0, the ERP system sends and receives data via IDocs. We deliver mappings to XML messages that are compatible with the IDocs. The table below outlines the mappings for these IDocs and XML messages

Process	Mapping of IDoc to XML
Process	Direction	IDoc	XML Message
Send purchase order from SAP ERP to SAP SNC	IDoc to XML	ORDERS.ORDERS05 Available as of SAP R/3 4.6C	ReplenishmentOrderNotification
Send purchase order confirmation from SAP SNC to SAP ERP	XML to IDoc	ORDRSP.ORDERS05 Available as of SAP R/3 4.6C	ReplenishmentOrderConfirmation
Send changed purchase order from SAP SNC to SAP ERP as part of approval process	XML to IDoc	PORDCH.PORDC02 Available as of SAP ERP 6.0	ReplenishmentOrderNotification
Send changed purchase order from SAP ERP to SAP SNC as part of approval process	IDoc to XML	PORDCR1.PORDCR102 Available as of SAP ERP 6.0	ReplenishmentOrderNotification
Send new or changed purchase order from SAP ERP to SAP SNC as part of Service Parts Management	IDoc to XML	ORDNTF.ORDINT01 Available as of SAP ERP 6.0	ReplenishmentOrderNotification

As of enhancement package 4 for SAP ERP 6.0, the ERP system can also send and receive some data directly with the XML messages without needing to map the messages to IDocs. The following table outlines the XML messages that can be used:

Process	XML Message
Send purchase order from SAP ERP to SAP SNC	PurchaseOrderERPReplenishmentOrderCollaborationNotification
Send purchase order confirmation from SAP SNC to SAP ERP	Use IDoc/XML Mappings
Send changed purchase order from SAP SNC to SAP ERP as part of approval process	PurchaseOrderERPRequest_V1
Send changed purchase order from SAP ERP to SAP SNC as part of approval process	PurchaseOrderERPReplenishmentOrderCollaborationNotification
Send new or changed purchase order from SAP ERP to SAP SNC as part of Service Parts Management	Use IDoc/XML Mappings

Note Note

When sending a changed purchase order from SAP SNC, you can use either the IDoc-compatible XML messages that were available in lower releases or the XML messages that do not require mapping . We recommend that you use XML messages that do not require mapping for standard purchase order collaboration and contract manufacturing procurement. You use the PO_PURORDERPREQ_SEND validation check to specify which XML message is sent. If the validation check is active, SAP SNC sends thePurchaseOrderERPRequest_V1 XML message. If the validation check is inactive, SAP SNC sends the IDoc-compatible ReplenishmentOrderNotification XML messages. The validation check is inactive in the standard delivery.

End of the note.

As of enhancement package 5 for SAP ERP 6.0, you can also send purchase order confirmations from SAP SNC to SAP ERP using an XML message without needing to map the message to an IDoc. The following table outlines the XML messages that can be used:

Process	XML Message
Send purchase order from SAP ERP to SAP SNC	PurchaseOrderERPReplenishmentOrderCollaborationNotification
Send purchase order confirmation from SAP SNC to SAP ERP	PurchaseOrderERPConfirmationRequest
Send changed purchase order from SAP SNC to SAP ERP as part of approval process	PurchaseOrderERPRequest_V1
Send changed purchase order from SAP ERP to SAP SNC as part of approval process	PurchaseOrderERPReplenishmentOrderCollaborationNotification
Send new or changed purchase order from SAP ERP to SAP SNC as part of Service Parts Management	Use IDoc/XML Mappings

Note Note

When sending a changed purchase order or a purchase order confirmation from SAP SNC, you can use either the IDocs-compatible XML messages that were available in lower releases or the XML messages that do not require mapping. We recommend that you use XML messages that do not require mapping for standard purchase order collaboration and contract manufacturing procurement. You use the following validation checks to specify which XML messages are sent:

PO_PURORDERPREQ_SEND
If the validation check is active, SAP SNC sends the PurchaseOrderERPRequest_V1 XML message. If the validation check is inactive, SAP SNC sends the IDoc-compatible ReplenishmentOrderNotification XML messages. The validation check is inactive in the standard delivery.
PO_PURORDERPCNFREQ_SEND
If the validation check is active, SAP SNC sends the PurchaseOrderERPConfirmationRequest XML message. If the validation check is inactive, SAP SNC sends the IDoc-compatible ReplenishmentOrderConfirmation XML messages. The validation check is inactive in the standard delivery.
