In Recruiting, Does HR Know Best?

In Recruiting, Does HR Know Best? I need some advice! I'm in a bad spot. I'm a new manager. I manage two people in a Data Services team. That means that we create reports for the other managers, Directors and VPs in our company. They say "Be careful what you wish for" and that is definitely true, because when our managers figured out how useful our reports are, they started to ask for new and different reports all the time!
