A practitioner has created an approval activity in a workflow. The multiple approval option is selected. The approval activity is assigned to a group of two operators. One of the operators approves the request and the other rejects. Which branch of the approval activity is run?

When the 'Multiple approval' option is enabled for an Approval activity in an Adobe Campaign workflow, the task is sent to all operators in the specified group. The workflow logic is configured to proceed as soon as a single operator approves the task. The first approval received triggers the 'Yes' transition, and the workflow continues down that branch. Any subsequent responses from other operators, including rejections, are then ignored for the purpose of path selection.

A. The No Branch is run. This is incorrect. The 'No' branch is only activated if all assigned operators reject the task, or if the approval deadline is reached without any approvals.
B. Neither Branch is run. This is incorrect. The workflow does not halt; an approval was received, which is a defined trigger for a transition, so one of the branches must be executed.
D. Both the Yes and No Branch are run. This is incorrect. A workflow activity can only activate a single outbound transition upon completion. It is logically impossible for both branches to execute simultaneously.

"Approval" activity:

Section: Action activities > Approval > Properties of the activity

Quote: "If the Multiple approval option is selected

the task is assigned to several operators (operators of a group or a list of operators). The approval of a single operator is enough to activate the 'Yes' transition." This source directly confirms that the first approval validates the 'Yes' branch

irrespective of other operators' actions.
