# Call a Business Process Using a Process Control

Part II of the tutorial demonstrates how simple it is to interchange calls to different external resources in your business process.

You learn how to design a call to another business process from your Request for Quote process. Specifically, you create a new Process control and change the asynchronous call to the Web Service you designed in Part I, making it instead an asynchronous call to another business process, via the new Process control.
