How many Start shapes can a single flow rule contain?

A single flow rule in Pega can contain only one Start shape. The Start shape acts as the entry point of the flow and is crucial for defining the initiation of the process. It establishes how and when the flow is executed, linking the flow to an event that triggers its start, such as a user action or an automated event.

Having a single Start shape ensures that the flow has a clear entry point and helps maintain the structure and readability of the flow rule. Allowing multiple Start shapes would complicate the flow design and could lead to ambiguity regarding the flow's initiation.

This design choice is important for ensuring proper flow management and maintaining the integrity of business processes modeled in Pega. Each flow should have a defined starting point to enhance both implementation and maintenance.
