Modifying resource availability from RPM resource dashboard

Hi Folks,

I am working on RPM 4.5. In the resource dashboard (Administration > Resources if using standard navigation), I am able to list out all my resources and edit the "general information", however the buttons "new" and "remove" for maintaining availability and location is greyed out. Any ideas on why I cannot edit this from the Portal?

If using transaction RPM_EMPDATA I am able to make changes, however the portal only display the info and the buttons are greyed out.

Thanks,
