This integration scenario enables you to simplify replenishment orders. SAP Supply Network Collaboration (SAP SNC) is the platform used by all participating business partners (customers, suppliers). The ReplenishmentOrderNotification and ReplenishmentOrderConfirmation messages are exchanged between SAP SNC and the supplier's ERP system within the Responsive Replenishment business scenario. At this point, SAP SNC takes over planning, while the supplier's ERP system takes over logistics execution.
