caching problem in sql reporting services

Hi all,
I have developed a web application which displays records stored in the database based on certain criteria supplied by the user. I have used SQL Reporting services for generating a report coresponding to the displayed records. The problem I faces is as follows.
I generated a report for the records displayed in the application. Then, I updated one of the records and again generated the report. But the change I made is not reflected in it. The report is the same as the one previously generated. But the change is reflected if I logged out of the application, again logged in and generated the report.
I checked the 'Execution properties' of the report in the Report Manager and I found that the 'Do not cache temporary copies of this report' option remains selected. But the caching problem exists. Please help if anyone knows a solution. I am desperately in need of a solution for the above problem.

Thanks,

Renju.

Had similar problem with SRS 2000 (are you using same version).

Resolved by creating a dummy parameter that passed the current date/time - forcing a new dataset everytime...
