A business function is an aggregation of sub-functions and processes. These sub-objects belong to the function and will be deleted if you delete it.

To create a business function, click the Business Function tool to select it, and then click in empty space or in an architecture area or business function in the diagram:

You can create sub-functions and processes inside the function by selecting the appropriate tool and clicking in the function symbol:

Business functions can have the following properties:
Property Description


Identify the object. The name should clearly convey the object's purpose to non-technical users, while the code, which is used for generating code or scripts, may be abbreviated, and should not normally include spaces. You can optionally add a comment to provide more detailed information about the object. By default the code is generated from the name by applying the naming conventions specified in the model options. To decouple name-code synchronization, click to release the = button to the right of the Code field.


Extends the semantics of the object. You can enter a stereotype directly in this field, or add stereotypes to the list by specifying them in an extension file.

Sub-functions and processes appear inside the function symbol, and are listed on the Children facet of its property sheet.
