Use in Manufacturing 
In manufacturing, the supply chain event management-relevant process manages the events that make up the entire production process, from planning to the end of production. You or your partners can report process steps during manufacturing. In this way, the transparency of the manufacturing process is ensured. In most cases, companies use this data only for internal purposes and internal transparency. To ensure the transparency of planned and actual events, you can, however, use SAP Event Management (SAP EM) to report events to external parties, for example, customers, subcontractors, or sold-to parties. You can use various information channels to report these events.
Example of Processing a Machine Breakdown in the Manufacturing Process
The following figure provides an example of a manufacturing process that is relevant to supply chain event management:
The line personnel (for example, the process operator) identify a machine breakdown and create an appropriate maintenance notification.
SAP EM triggers the creation of an SAP APO alert that informs the production planner that one of the production orders that have been scheduled (released) for this line is at risk of not being processed.
SAP EM tracks the processing of the malfunction notification to the point when the malfunction has been repaired.
You can evaluate the effects at a later time. For example, you can check the number of production orders that had to be rescheduled, and, in this way, you can draw conclusions about the quality of the original planning.
