And I can't see details, but I looked at it yesterday deeper, and I think data connection is not available, but I can't figure out how to check there data connection is pointing as some of the data connections has "edit" option and this one doesn't. I guess if I would be able to repointed to a new connection it would work, originaly is pointing to a cube file, but not sure how to change it.
