I have created a .unx - universe based on BeX query and this BeX is related to the ECC data base ,now i need to create a WebI report by using this .UNX ,

But when i try to drag the objects in to my WebI report and run it is showing pop up message related to estimated time and keep on processing without displaying data in my WebI report (now I am using SAPBI4.0 launch pad ) ,

Please help me .
