about update requests to several people

I don't know how to deal with this question.

when the user submitted a form , then request was set to send several people to update few fields of the form. and when any one of these people updated it , then others doesn't need to updated it.

and we need to know how updated it.

But i can find the way to delete or deny others people's not executed tasks.

What's the best practice?
