You also should be aware of the following information:
Each SAS Web-based application, such as SAS® Web Report Studio and SAS® Information Delivery Portal, must run in a unique browser session. If you attempt to share one browser session across multiple tabs, you will experience unpredictable application behavior. For example, when switching between tabs, you might be repeatedly asked to log into the application.
In addition, do not attempt to run SAS Web Report Studio in multiple browser sessions on the same computer.
Also, if you are navigating between linked reports, there should be a link to return to the previous report in the target report. Do you not see that link?
