• The conceptual model for this process is
  illustrated below
• The Replenishment System generates order requests
  which are subsequently entered into the ERP
  System.
• The ERP system then creates a purchase order (PO)
  corresponding to each request and sends the PO to
  the appropriate supplier.
• The supplier then sends back an acknowledgment
  that it received the PO.
• Once the ERP system receives the acknowledgment,
  the Replenishment System needs to be updated to
  reflect that the request has been accepted.
