Sending Confirmations from the Supplier System
to SAP SNC 
In SAP Supply Network Collaboration (SAP SNC), the supplier can create confirmation schedule lines and (for subcontracting) component requirements for a customer purchase order by sending the confirmation data with a ReplenishmentOrderConfirmation XML message from his or her back-end system to SAP SNC. The supplier must always transfer a complete purchase order with confirmation schedule lines to SAP SNC. Purchase order collaboration does not support change transfer.
● In Customizing for Supply Network Collaboration, under Basic Settings ® Processing Inbound and Outbound Messages ® Process Types for Inbound Messages, you have set the Supplier Collaboration (SNC) process type for ReplenishmentOrderNotifications. You can set this process type as the default process type or as sender-dependent and recipient-dependent.
● You have activated the validation check Creation of Confirmation Schedule Lines for Purchase Order Item Is Allowed (POCONF_CONF_ALLOWED) and thus ensured that SAP SNC only allows confirmations under the following conditions:
○
The
confirmation
control allows confirmations.
○
A
work order has not
yet been created for the purchase order.
● The supplier must specify the components of a confirmation schedule line in the same sequence as in the original subcontract order.
When the purchase order arrives in SAP SNC from the supplier back-end system with confirmation data, it firstly receives the distribution status Updated by Supplier. SAP SNC automatically publishes the ReplenishmentOrderConfirmation, thereby giving the purchase order the distribution status Publishedby Supplier. The purchase order can no longer be changed. Without the approval process, SAP SNC immediately sends a ReplenishmentOrderConfirmation to the customer back-end system.
In the standard system, SAP SNC sends the
XML message directly in the background. However, you can also change the
configuration so that SAP SNC uses the Post Processing Framework (PPF) to send
the XML message. For more information, see
Publication of XML
Messages.
In the standard system, SAP SNC also accepts confirmations from the supplier back-end system for purchase order items that are not changeable on the Web UI for SAP SNC, in other words, for purchase order items for which the supplier is not allowed to create confirmations on the Web UI. However, you can also make settings so that the supplier is only allowed to send confirmations to SAP SNC for an item if he or she is allowed to create confirmations on Web UI. To do this, activate the validation check Creation of Confirmation Schedule Lines for Purchase Order Item Is Allowed (UI)(POCONF_CONF_ALLOWED_AS_UI).
