Creating a composite process

Chapter 6 Building an Analysis Business Process Model

You can create a composite process in any of the following ways:

From the symbol of the parent process, using the diagram or the contextual menu of the parent symbol. The created default sub-process diagram is empty. You can then add objects to fill its content.
From a selection of symbols in the diagram, using the Tools→Create Composite Process command. A sub-process diagram is automatically created and is filled with the symbols you have selected.

A composite process must always have one start and one end at least.
