I am a newbie to OBIEE and trying to learn. I have created a sample repository based on SUPPLIER2 oracle sample database. I have create the physical, business & presentation layer catalog. I can also see SupplierSales subject area in Answers and no errors in global consistency check. But when I expand Product dimension it throws an error saying "There was an unknown error with the server call", while it is allowing to expand other dimensions.
What could be the cause of this error? Why is it allowing to expand other dimensions & not Product dimension?
