I know that whenever there is an approval step in the workflow, and a group of operators assigned to be able to approve, the first one to respond is who defined the outcome. But is there a way to set up the approval to gather the feedback from all reviewers?
And what would happen if some approve and some reject?
Example: I have dragged the Approval control to my canvas and selected the "Multiple approval" option for the Campaign Managers group.
Does that mean that the workflow would wait till all of them have responded?
Yes it should wait until they have all responded and the Yes branch should only execute if they all approve. You can test this to confirm the behavior works as expected. (And thanks for using the forum!)
Though this question seems quiet old, but can be useful to other forum users
If One of the operator approves the request and the other rejects, both the branches will execute and the workflow will not wait on the approval activity for all the responses, it will be in started state and will keep execution in progress as soon as it gets its first response (approval/rejection).
If approval comes first, the yes branch will continue the execution further and as soon as rejection comes, the no branch will also start execution and vice versa.
You can see this in below screenshot, as soon as the no response came from an operator, the workflow started running and again yes response came from other user and the yes branch started its execution.
