No Oauth option on service

Hi all,

Im working on a report based on a Projects Online environment. And used the content pack as a headstart. But the content pack is trying to load all data; loading that in took about 17hours.. So i edited the odata string to use some filters like this: 

So in this case im using parameters to define what year to get from the odata feed. However, when i publish this the option to use oauth on the service dissapears; and i can not automatically refresh the report. But i can login using my org. account on the desktop version.

So the question is; do you experts know a way to not load all data, but still use an oauth connection?
