What functionality is used to pass data between a subflow and a flow, subflow, or script?

The functionality used to pass data between a subflow and a flow, another subflow, or a script is best described by inputs and outputs. When creating flows or subflows in ServiceNow Flow Designer, inputs and outputs serve as parameters that facilitate the transfer of data. Inputs allow data to be fed into the subflow from the calling flow, while outputs enable the subflow to return data back to the calling flow once its execution is complete. This two-way data exchange ensures that flows and subflows can communicate effectively and allows for more modular and reusable design.

Data Pills, while relevant in the context of manipulating data within a flow, do not define the specific mechanism for passing data between flows or subflows. They are more about representing variables and values within the Flow Designer interface. Execution Details provides insights into the runtime properties of the flow but does not actively participate in data transfer. Flow Logic pertains to the structure and organization of the flow, including decisions and branching paths, but it does not specifically address data passing.

Thus, understanding the role of inputs and outputs is crucial for effectively designing and managing workflows in ServiceNow's Flow Designer.
