Model a diagram of type BPMN collaboration diagram (BPMN 2.0) as shown in the figure:
There are three types of connections between process and data:
The input data for the process are linked to a Message start event via the has as output connection.
The output data of the process are linked to a Message end event via the is input for connection.
The process data do not have a connection to a modeled item. Process data are implicitly input and output data for all process steps in the diagram.
Models of the Screen design (Solution Design) type are exported if they are assigned to a screen object that is linked to a user task via the is represented by connection in a function allocation diagram.
The user task must have an occurrence in the diagram of type BPMN collaboration diagram (BPMN 2.0) and have an assignment to this function allocation diagram.
An object of the Screen (Solution Design) type must be linked to an object of the User task type in the diagram of the BPMN collaboration diagram (BPMN 2.0) type.
Each user task must be assigned a function allocation diagram. The user task must be linked to an object of the Screen (Solution Design) type in this function allocation diagram.
