What happens when the Last Action in a subflow is reached?

When the Last Action in a subflow is reached, the subflow will exit automatically. This means that once the final action in the subflow has been executed, control is returned to the point in the main flow where the subflow was called. There is no need for an explicit exit command to terminate the subflow, as this is handled automatically by the Power Automate platform. This behavior allows for streamlined flow execution and reduces the complexity of managing flow state transitions manually.

This automatic exit ensures that once the intended set of operations in the subflow is complete, the main flow can continue its execution without additional intervention or command necessary from the developer. This characteristic of subflows makes them a powerful tool for organizing logic and reusing workflows efficiently in Power Automate.
