Class Search and Enroll -> "you have no scheduled classes available in class search"

In Peoplesoft Campus Solution → manage classes tile, when I click on "class search and enroll" it says, "you have no scheduled classes available in class search", but the class is scheduled in term and also the student is activated in that term. All the configurations which is required for class search are also completed. Can anybody tell me is there any other step which I am missing? Or is there any data related security required for fluid tiles?
