It’s important to know that the UI is part of the executable business process. The UI implements the Enter Request Data step. After a manager approves the request, you continue to the Create Purchase Order step. Now the time has come to actually write the data into the back-end system. Again, start with the definition of the interface. In this example, the composite wants to hand over the data asynchronously. Therefore, your interface contains only input parameters — no output parameters. You only submit the selected product with its quantity resulting in interface in the code below.
