Decomposing an Atomic Process

You can decompose an atomic process in a business process diagram using its icon, context menu or property sheet.

Press CTRL and double-click the process symbol (this will open the sub- process directly).
Right-click the process and select Decompose Process in the contextual menu.
Open the property sheet of the process and, on the General tab, select the Decomposed Process radio button.

For more information about process decomposition in a PHD, see Building Process Hierarchy Diagrams.

When you create a decomposed process, a sub-process diagram is automatically created below its entry in the browser:

The decomposed process is empty at first, except when you create it from a selection of symbols. Any objects that you create in the sub-process diagram are listed in the Browser under the decomposed process.

In a BPD, decomposed processes must always have at least one start and one end.
