Application Process
An event means that an object has taken on a state that affects the process
A function is a task or action performed on an object to support one or more goals
An operator connects functions and events
Application Process
Events trigger functions and are the results of functions.By arranging this event-to-function change in a sequence,so-called event-driven process chains (EPCs) are created.An event-driven process chain (EPC) shows thechronological-logical procedure of a business process.

Otherwise, it is rejected. Furthermore, the credit check is carried out by the financial department, the goods availability check by the warehouse department, and the order acceptance/rejection is done by the sales department.
Construct an EPC diagram for this case.
