How many Start shapes can a flow rule typically contain?

In Pega, a flow rule serves as the blueprint for processes and workflows that guidance through business logic. The Start shape specially indicates where the flow begins. Typically, a flow rule contains one Start shape because it defines a single entry point for the flow.

Having more than one Start shape would create ambiguity, as it could lead to confusion regarding which path should be followed. A well-structured flow ensures clarity and simplicity, allowing for better maintainability and understanding of the overall process. Hence, the design of flow rules inherently supports only one Start shape to maintain a clear and defined point of initiation for the processes involved.
