Multiple Assign Flexi Task - Send no longer required Email if main approver outcome received

If I get it right the only reason to have multiple felxi-tasks is to have different emails and different outcomes for the approver right?

My first question would be, what are the differences for the 3 reviewers? Why do you need 3 different flexi-tasks? Are there different emails? Because if not I would do all reviewers in one flexi-task and collect their comments if there are some.

Second I would check after each decision the approver makes with either a separate nested workflow or inside each outcome in a group of actions if the task or tasks of the reviewers already got any outcome. You can do that by query on the workflow task list on the task IDs which you store to a variable when the flexi-task is created.

Then you can complete the reviewers tasks with a third outcome using a web service with a seperate created notification afterwards if there are no outcomes yet and approver already made his decision.

If one or more reviewers already have an outcome you can skip that notification to do nothing or inform him, whatever fits your requirements.

I know the solution isn't the most beautyful one but I do not have any other idea here and I am not sure if I misunderstood something or if my solution would work out perfectly. This is just my first shot...

@ellie5225 ....did you try using stop workflow or terminate workflow action? I believe it will send the notification that your response is no longer needed.
