The image shows a Start step at the top. The Start step has two outgoing control flows: one to a Transformation 1 step and the other to a Transformation 2 step. The Transformation 1 step has an incoming data flow from the left side of the role and an outgoing data flow on the right side of the role that connect to a Transformation 3 step in another role. The Transformation 1 step also has an outgoing control flow that connects to the End step. The Transformation 2 step has an outgoing data flow to a port on the left side of the role. The Transformation 2 step also has an outgoing control flow to the End step and an outgoing control flow to the Transformation 1 step. In the second role to the right of this role, the Start step has an outgoing control flow to Transformation 3. Transformation 3 has an incoming data flow from Transformation 1 in the first role. Transformation 3 also has an outgoing data flow to a Split step. The Split step has an outgoing data flow that goes to another role on the right that is not shown. The Split step also has an outgoing data flow that goes to Transformation 2 in the first role. The Split step also has an outgoing control flow to the End step. End of description.
