permissions issue with http driven report in web iframe

Hi there,

I need to understand why I am getting the following error when I run my deployed (remote) report embedded in an iframe within a page of my web application.

error:
An

error has occurred during report processing. (rsProcessingAborted)
Query

execution failed for data set 'cnMOOR'. (rsErrorExecutingCommand)For

more information about this error navigate to the report server on the local

server machine, or enable remote error

This happens when I fire the following code from a commandbutton:
AppSettingsReader cfgApp = new AppSettingsReader();

string prefix = Convert.ToString(cfgApp.GetValue("reporturlprefix", typeof(System.String)));

string reporturl = prefix + "Client&rs:Command=Render&rs:Format=HTML4.0&rc:Parameters=False&supplierid=" + Session["supplierId"].ToString() + "&clientid=" + ddlClient.SelectedItem.Value + "&startdate=" + txtStartDate.Text + "&enddate=" + txtEndDate.Text + "&ownertype=1";

SpecificClient.Attributes.Add("src", reporturl);

SpecificClient is the ID of the Iframe

on the same page I created a link - which runs the report perfectly - no permission problems.
<a href="http://server2003msrs/reportserver?/moorreports/Client&rs:Command=Render&rs:Format=HTML4.0&rc:Parameters=False&supplierid=28&clientid=71&startdate=2007-01-01&enddate=2007-02-16&ownertype=1">Test</a>

I don't understand why these two controls are behaving differently.

I'd appreciate some guidance with this as the deadline looms...

Hi there,

something that I didn't mention - this error only happened when I changed the connection string properties. Previously both controls had worked fine.

I eventually fixed it by creating a new report whilst pointing at the new database.

suddenly all of them worked as before.

weird, but that's what solved the issue.
