.NET SAP Crystal Report Error "The report you requested requires further

We have Have Installed the SAP Crystal Report on our ASP.NET application. Every thing is working fine in Developement and Test Enviornment . But in live we are getting a Error saying "The report you requested requires further information." If we restart the IIS, this error wont come for a some time. But after that, the same error appear again. Then it requires an IIS restart.

With resepect to code wise. We are using datatable. Crystal Report is not directly connected to Database. We are Binding the Datatable to the report. This error is occuring only after installing the SAP Crystal Report. But in the old version of the Crystal Report is was working fine.

Please can any one help us.
