I'm not sure I fully understand. You have a screenflow that should do routing? Wouldn't that require more of a traditional flow? So you'd want one screen flow for the initial item entry and you'd call that as a subflow, and then once the operator has collected what you need, you'd route the item in the main flow to the manager who would pick it up and perform the action in a second screen flow (which may call some of the same sections). Or am I misunderstanding your question?
Thanks for the update.Interviewer did not mentioned to call the screenflow as subflow form Main flow,but his mentioned only to route the WO after some action on second screen out of 5 screens in a screen flow,but in screen flow we are configuring routing on Start shape itself in Screen flow.So my question is ,Is it possible to Route to Manager after performing action in second screen?
