Unable to access data preview of attribute view

HI

I have query like while accessing the data in Attribute view, i am getting the error as

Cannot get the data provider outline

cannot perform datapriview,     either connection to Database is unavailable, or project is not shared

1) I have checked the connection is available

2) Like we access the tables data in data preview , cant we access data of Attributeview without sharing it.

Gone thru the links regarding data preview error(2048 Column store error:search table error)

But no proper answer for same.

Thanks, MBR
