How can data flow between a screen flow and a local action?

In the context of how data flows between a screen flow and a local action, the process of setting the action's inputs and outputs is key. When a screen flow is invoked and it calls a local action, the local action can receive data from the screen flow via input variables defined for that action. This allows the screen flow to pass information necessary for the action to execute effectively, such as parameters or user selections made on the screen.

Moreover, local actions can also send data back to the screen flow through output variables. This data exchange is crucial for maintaining context and continuity within the flow, enabling dynamic and responsive user experiences. By effectively managing these inputs and outputs, process automation can be tailored to meet specific requirements and respond appropriately based on user interactions.

Other methods such as using global variables or custom settings do not establish direct communication between a screen flow and a local action in the same structured way. Global variables serve as shared data across flows but do not facilitate specific communication in the same context as input and output parameters. Scheduled flows are typically asynchronous and operate independently of user interactions in a screen flow, making them unsuitable for this immediate data flow scenario.
