Hi,

We've had a slight issue with our HR reps not being able to see salary/ bonus info for all colleagues that sit within their AOR and im wondering if anyone has had a similar experience and can recommend any ways around it? 

The users are using the act as proxy manager functionality to go in and review pay information for the different teams in the area they support, usually proxying in as the highest level manager in that area to see the colleagues that report into them. The problem though is that they then cannot see the plan details for that highest level manager theyre proxied as because the managers of colleagues at that level sit in a different organisation outside of the AOR of the HR rep.
