Facebook and Twitter analyzing data

I followed the facebook instructions for microsoftbi and got popup limit to 100 and resolved using advance editor. but I see only 4 fields like created_time, id, message and story. I don't get all the other fields as shown in this link.

I tried my facebook as Me and didn't get much details. I got just only Post as I have selected only Posts. Do we get only 4 fields like as I mentioned. If I want to get everything of Me like posts, Likes, comments, friends.

I tried with friends and got only three friends names.. Why all these discrepancies..

Any idea.

Thanks,
Thimma
