SSRS report reverts back to parameter screen when you click Apply after entering parameters

I made a simple report that works in the designer but if you try to run it in a browser it reverts back to the parameter prompt after entering parameters and clicking Apply. I don't get any errors and like I said, it runs in the designer.

What is the difference between a click through and a drill through report in ssrs?

I was asked this question yesterday and I didn't know the answer. I'm a total ssrs noob so if you could explain it thoroughly that would be helpful.
What is the difference between a click through and a drill through report in ssrs?
Clickthrough Reports
A clickthrough report is a report that displays related data from a report model when you click the interactive data contained within your model-based report. These reports are generated by the report server based on the information contained within the report model. The person who created the model determines which fields are interactive and which fields are returned when a clickthrough report is opened. These field settings cannot be changed in the report authoring tools.
Clickthrough reports are auto generated. However, you can create an alternative customized report to the model for interactive data items that is displayed instead. The custom report is a standard Reporting Services report.
Drillthrough Reports
Drillthrough reports are standard reports that are accessed through a hyperlink on a text box in the original report. Drillthrough reports work with a main report and are the target of a drillthrough action for a report item such as placeholder text or a chart. The main report displays summary information, for example in a matrix or chart. Actions defined in the matrix or chart provide drillthrough links to reports that display greater details based on the aggregate in the main report. Drillthrough reports can be filtered by parameters, but they do not have to be. Drillthrough reports differ from subreports in that the report does not display within the original report, but opens separately. They differ from clickthrough reports in that they are not auto generated from the data source, but are instead custom reports that are saved on the report server. They differ from drilldown reports in that they retrieve the report data only for the specified parameters or for the dataset query.

SSRS URL Access slower than Report Manager

I am using URL access to embed a report in an application using a URL that looks something like this:
https://servername/ReportServer/Pages/ReportViewer.aspx?/ReportPath/&parameter=value
This report has several parameters whose valid values are populated by queries.
The report is displayed in about the same amount of time as it takes when accessing the report via Report Manager.
However, I've noticed that if I change a parameter in Report Manager and click the "View Report" button, it refreshes a few seconds faster than if I refresh the report by URL access.
I assume this is because refreshing the report in Report Manager cuts out some processing steps. It looks like a bunch of state is sent back to the server when you refresh the report using the "View Report" button in Report Manager, whereas I presume refreshing the report via URL access is essentially doing all of the work from scratch.
Are my assumptions correct? Is there any way I can refresh a report with new parameters via URL access just as quickly as it does when using Report Manager?
You're assumptions are correct, as far as I know the Report Manager and ReportViewer controls will have a session spanning multiple requests. (Although I'm a bit surprised this would also work when you change the parameters, because I can't imagine what steps could be skipped in that case.)
To control this, the Report Manager uses sessions. Even though I haven't tried it myself, you should be able to do this with URLS by using the SessionId and related parameters.
Let us know if this worked for you!

SSRS Report in CRM 4 IFrame not updating

I am using CRM 4 and have uploaded an ssrs report into the reports area. I published this for external use and in one of the entites have an iFrame that points to this published report.
This all works well, the problem is that if I update some of the info that the report is looking at and refresh the page the report doesn't update.
In fact I need to close the browser and re-open it of the report to refresh. This only happens in the iFrame, if I re-run the report in the reports section it updates correctly.
I assume this is because the info is cached somewhere. Does anybody know if there is a way to force CRM/SSRS to get the info afresh every time?
Thanks,
Neil
You need to add an additional parameter to the end of the URL used as the IFRAME source
&rs:ClearSession=true
This forces a refresh of the report each time it is accessed.
