Flow variables are tied to which scope?

• A. Across The Entire Application
• B. Current Flow Only
• C. Within The Current Transaction
• D. Across Server Lifetime

Answer: (B)

Flow variables are scoped to a single flow invocation. They exist while a message is being processed in that flow and can be read or updated by any component within the same flow, but they don’t persist once the flow finishes or the message moves to another flow. This makes them ideal for carrying intermediate data through the steps of a single flow without leaking into other flows or lasting beyond the request.

They aren’t application-wide, so they aren’t available to other flows or requests. They don’t tie to a transaction boundary or to server lifetime, so they won’t survive across different transactions or a server restart.
