I'm working on an existing Zen Report that uses queryClass/queryName to retrieve data using a class that has a Stored Procedure method. Which works fine. I have created second class with a Stored Procedure method, I modified the zen report to use this class and now I'm having the following error.  
Error: SQLCODE: -99 Message: User UnknownUser is not privileged for the operation
ErrorNo: 5540
