As part of my role as Deputy/Assistant Commissioner I am delegated tasks by my Commissioner, but I do not have these permissions on Compass, why is this?

Compass permissions can only be set up so that everyone with the same role has a certain permission or no one does, it cannot be  changed on an individual basis. With permissions such as Commissioner approvals, these are not available to Assistant or Deputy Commissioners. Where possible, and inline with POR, delegation can still take place, but the Commissioner will have to complete the parts of the process that involve Compass.
