What happens to subflows in Power Automate when they finish executing their last action?

In Power Automate, when a subflow finishes executing its last action, it automatically exits without the need for an explicit exit action. This is a built-in feature that allows for seamless execution and flow management. Subflows are designed to encapsulate sections of logic that can be reused across multiple flows. Once the last action in the subflow is completed, control returns to the parent flow, allowing it to continue processing without requiring any additional steps to terminate the subflow.

This streamlined approach enhances the efficiency of process design by minimizing the need for additional code or actions that would normally be necessary to manage the flow of control. The subflow's exit happens automatically, which simplifies the overall orchestration and helps maintain clean and understandable flow diagrams.

Other choices present misconceptions about subflow functionalities in Power Automate. For instance, requiring user intervention to exit contradicts the intended automation principle. Rerunning actions indefinitely and becoming inactive until called again also misrepresent how subflows function by implying a need for manual control or inactivity, which is not how Power Automate is designed to operate.
