Business Process Type 
The business process type is a classification of business objects or business processes in the application system for which you want to manage events in SAP Event Management .
You need the business process type to determine the business objects, business processes, and relevant changes ( events ) that are relevant to supply chain event management (SCEM-relevant) (see also Application Object Type Determination , Event Type Determination ). You assign a business process type to each business object in the application system.
The system needs the business process type as the main criteria for assigning an application object type to an event handler type. In this way, it can create event handlers and update them. For example, the system needs the business process type to find the corresponding event handler for incoming event messages. If the business process type, which the application system transfers to SAP Event Management for an SCEM-relevant object, matches any of those saved in the event handler, SAP Event Management processes the event message and updates the event handler.
SAP delivers a selection of business process types with SAP Event Management. You can also define your own business process types in Customizing in the application system and in SAP Event Management.
Recommendation
We recommend that you use a remote call to compare all business process types for processing in SAP Event Management with all those in the application system. The business process type is the only parameter that is found in both systems. SAP Event Management uses this parameter to find the event handler type and creates an event handler if the business process type is the same.
Examples of business process types include:
A sales order
A purchasing transaction
A manufacturing order
A shipment
A delivery
The following figure gives you an example of the link between the business process type and the business object:

In this example, there are four business objects, two of which you have defined as being SCEM-relevant:
You track the business process for processing a sales order. You consider the sales order as a whole. You have assigned the business process type Sales Order to it.
You track the container that transports the goods. You have assigned the business process type Shipment to the shipment, since the handling unit container belongs to the shipment.
