What happens every time an action is added to a flow?

When an action is added to a flow in ServiceNow Flow Designer, data pills are created to represent the data that is being manipulated or generated by that action. Data pills are the variable containers that hold information, allowing users to pass data between different actions within the flow. As each action is added, relevant data pills correspond to the outputs of that action, enabling the flow to access the necessary information for subsequent actions.

This creation of data pills is fundamental for maintaining the flow's logic and ensuring that the right data is utilized at each step, thus enhancing the flow's overall effectiveness in automating processes. The data pills provide a visual way to handle and reference values, making the design process more intuitive for users.

In contrast, the other options do not accurately describe the outcome of adding an action to a flow. While runtime variables may store data during flow execution and execution time is an important consideration, neither occurs simply by adding an action. Additionally, flows do not automatically publish upon adding an action; users must explicitly publish the flow after making their changes to make it active.
