Rep-51019: System user identification is missing

Hi All,

When I try to print a report when called from a form, is get the following error: Rep-51019: System user authentication is missing. When I enter username as weblogic and enter weblogic's password and hit enter, report parameters screen is displayed. When I press the 'Submit Querry Querry "button, I get the error 'Rep-51018: Database user authentication is missing. When I enter the user's crentials and press'Submit Querry' button again, the Report Parameter is displayed again. When I press the 'Submit Querry' as new error message is displayed: Rep-163: The value for the destype is invalid."

However when to reun the report again, It prints ok. Without the error. This is valied for the entire session of the IE. If you close IE, then the error starts again. Its on the send run of the report (after  the entry of the system user authentication is satisfied) when the report runs. This is very cumbersome and very insecure since every user must know the weblogic/Password pair.
