You can create a data flow to specify the functions, constants, and events from which the selected function or selected event receives data.
Prerequisite
The object for which a data flow is to be created is an event or a function.
Data flows have to be created for objects with the Event (process instance started), Human task, Automated task, Notification, and Live message symbol type.
A human task must be connected to both a dialog and an organizational unit (Role, Internal person).
An automated task must be connected to an application system type.
Procedure
Open the relevant model.
Activate the Governance tab bar.
Select the object for which you want to open a data flow.
Click Create data flow.
An additional area for modeling the data flow is displayed. The system automatically checks whether the minimum modeling conventions for creating a data flow exist. If they are met, the object occurrence is automatically created in the data flow diagram. The data flow diagram is automatically assigned to the selected object in the business model.
In the modeling area, click the object that is to provide input data for the data flow, and hold down the mouse button. Place this object in the modeling area of the data flow.
Mandatory fields are marked with in data flow diagrams. Functions, events, variables, and constants can be input data.
Select the required input or output variables and/or constants for the function.
Model connections to represent the relationships.
You have created and modeled a data flow.
Tip
In the modeling area, you can also right-click the object that is to provide the input or output data for the data flow, and hold down the mouse button. Place the object in the modeling area of the data flow and select Paste source.
