Transaction Iview Giving HTTP 500 error, intermittenly.

Hi,

I have configured SSO between portal 7.02 and SAP ECC system for displaying few ECC Transaction Reports on Portal.

On portal, i have used SAP Transaction Iviews to display the SSO Configured Reports under one Portal Role.

The issue i am seeing is, whenever i access these reports one after the other, I end up in getting HTTP 500 error for some reports.

But on clicking again the same link, in portal it works without any error.

Please let me know, if you have any idea of how to get this resolved, reports should not throw any HTTP 500 error on random access of all 4 reports in any order and multiple times.
