Attached is the scenario provided in one of the self-study material.
W.r.t attached screenshot, there is a requirement where in the "The recruitment team work group managers are reporting to the recruitment coordinator". Hence as per solution provided in PDN is that the operator ID of Recruitment Manager will have the Reports To as "Recruitment Coordinator".This will work fine as long as there is only one Recruitment Coordinator.
My doubt is what if there are more than one Recruitment Coordinators.e.g:3. In that case we will not be able to use the OOTB routing functionality? If so,please explain
