In order to prevent subsequent flows from running if a flow is on a schedule, you would typically need to do the following:
1.
Get the Current Flow and Flow Run ID: You would use the Prefect context or the client API to retrieve details about the currently executing flow run. However, through the document excerpts provided, the exact method to obtain the current flow's run ID from within the flow itself wasn't directly referenced.
2.
Check the Schedule Status: You would check if the flow is scheduled and whether there are any other flow runs scheduled after the current one. This might involve querying your flow runs and examining their scheduled start times.
3.
Conditional Logic: Based on the schedule and current run information, you would implement logic to stop the execution or prevent the scheduling of further flow runs.
Unfortunately, the excerpts provided from the Prefect documentation don't seem to directly answer your question in totality. Since flows and flow runs are central concepts in Prefect, further investigation in the documentation or an example code showing how to use the Prefect client to interact with run metadata might be helpful in giving you a comprehensive answer.

For more specific use cases or code examples, I'd recommend searching the Prefect GitHub issues or asking the question there for guidance from the Prefect community.
