In this step you create artifacts that allow you to provide additional information in your business process model. The type of artifact used in the current business process model is a data object. It shows how data is used by the activities in the model.
From Palette , expand Artifacts .
Choose Data Object and click the modeling surface.
Your data object appears in the place you clicked.
Assign a name to the data object. To do that, open the General tab page in the Properties view.
In the Name field, enter Book_order_details .
Create Book_replenishment_form and Customer_details_form data objects. To do that, repeat the above steps.
Data objects you create have a default data type string assigned to them, which you can change.
