You can convert a default sub-process to a Reusable Sub-process, or Call Activity (in BPMN).
1. Right-click on the Sub-process to convert, choose the Sub-process type option and then click on Reusable process.
The diagram element's border will change to indicate it is now a reusable Sub-process.
If you have already diagrammed the Sub-process you will receive a message alerting to this fact. Click the Yes button to convert it and keep all the lower level diagram elements.
It is important to clarify that a reusable Sub-process calls a separately modeled process.
There are two different ways of creating a call to a reusable sub-process. The Edit Sub-process option opens an empty diagram workspace and relates it to the shape. Alternatively, you can manually relate the shape to a predefined diagram.
Let us assume that the Quotations Sub-process is reusable and has not yet been diagrammed .
To create a call for the Sub-process not yet model (i.e., create the detail in a new diagram), use the Edit Sub-process option by right-clicking the shape:
2. To reference an existing diagram (assuming Quotations detail was created in the previous step), relate the diagram in the Sub-process properties.
To do this, right-click on the Request Quotations reusable Sub-process element and select Properties from the display menu.
3. The Element Properties add-on window will display. On the Basic tab, in the Process drop-down list, select the predefined created Diagram.
