Use in Procurement 
The supply chain event management-relevant (SCEM-relevant) process in procurement begins with the creation of a purchase order for a planned material and ends with the transfer of data to a data warehouse system. You can evaluate the data there.
When you create a purchase order for a buyer with or without a reference document, the application system sends this purchase order to the supplier. If the supplier can fulfill the order, he or she confirms it. If not, he or she sends an appropriate notification to SAP Event Management (SAP EM). SAP EM sends an alert to the buyer. When the supplier has finished production, he or she sends an advanced shipping notification (ASN) to the application system.
All those involved in the process report various events to SAP EM, for example, that the ASN was sent. SAP EM also tracks the events that occur during goods receipt, invoicing, and the payment process. You transfer the relevant data to SAP NetWeaver Business Intelligence to evaluate it analytically.
To track the partner delivery, for example, you can connect the SCEM-relevant process in procurement with the process from transportation or order fulfillment.
The following figure provides an overview of using SAP EM in procurement:

An example of a procurement situation
A manufacturer of electronic goods orders customer-specific semiconductors in Singapore. The freight forwarder takes the delivery to Malaysia by truck and then by ship to the manufacturer of electronic goods.
Within this process, various partners report events to SAP EM using various means of communication. Examples include the Internet (portals), EDI, and radio frequency devices. By reporting events during the different phases of the process, the partners help to provide transparency across the entire business process.
Only the manufacturer of electronic goods who placed the order has an SAP system. The partners have different systems. The data in SAP EM is updated either by means of an Internet connection that the manufacturer of electronic goods supports or by means of EDI transactions.
