SSRS Updating Report when Dataset Query changes - reporting-services

I have a report which draws from dataset X. I have updated the query in dataset X by limiting the date from no restriction to past 24 hours.
Now that the dataset has changed, how do I make sure the data within the report is also up to date- i do not want to recreate the report as it had a lot of formatting that i did.
Any ideas?

Solved. Basically you have to clear cache

Combining multiple drill through reports into one

First time posting here so please be kind.
I've come from using PowerBI to achieve pretty much everything I need to with a couple of clicks to using SSRS 2008... and I'm having a hard time. Here's what I'm trying to do:
I have a main report that summarizes some data on how long it takes to close down help desk tickets. On that report I have a table with summary figures (ie 220 tickets were picked up after 5 working days, 18 tickets were reopened etc). I want to click the text-box that contains 220 and be taken to a drillthrough report that contain the same table with column headers and just different row sets in each case. There will be 8 drill through actions in total and I currently have 8 drill through reports. Only 2 of those are parameter based, the others just filter the dataset based on some conditions.
What I'm trying to work out is this: can my 8 drill-through reports be rolled into one, if they're just different views of the same dataset? I've created some calculated columns with values (Yes/No because boolean doesn't allow multiple values) which are easier to pass to parameters. I also have 8 parameters on my detail data set. I've set up actions (where parameter1 = yes for instance) to take me to my detail report and use the corresponding parameter each time. It should work... but it doesn't and I can't work out why. Currently its' complaining that I can't compare a boolean to an int16 - neither the value in my calculated column nor the default parameter value is boolean or int. So, am I trying to do something that just isn't possible? Has anyone else achieved this?
Edit: here's the parameter
The error I'm getting is
The calculated column that should be checked against the parameter is
=IIF(IsNothing(Fields!DatePickedUpByAgent.Value), "Yes", "No").
Here's how I defined the action to take me to the drill through report in this case
Here are the filters on the subreport dataset based on the parameters passed through from the main report. "NotYetPickedUpByAgent" is the example we've been discussing here. enter image description here
Could you please go through each of your parameters one by one.
I would suggest deleting all the filters and trying to run the report and subreport.
Then keep adding filter one by one.
I think issue can be any of the filter and not the one you think.

SSRS: Subscription column order differs from Report

I have a report, that used to have columns in the following order [A,B,C,D,Banana,E]. I was then asked to make some changes to my report, which I did so that the report columns now has an order of [A,Rocket Ship,Banana,B,C,D,E].
When I look in Visual Studio or look at the report on SSRS, I see the correct order, HOWEVER, when I let the subscription run, I see that it is still putting out reports with the wrong columns. Has anyone else seen this phenomenon? I've tried creating a brand new subscription, but I still get the old Column order.
Any help is greatly appreciated.
Check to see if the report using any caching or snapshots.
It might be using an old copy - though I would think it would be the same as one rendered manually from Report Server.
The issue is that the CSV report that is created isn't dependent on the report that is created with SSRS. Essentially, it just spits out the results of the SQL query into a CSV file.

how is ssrs parameter getting set?

I have an ssrs report that uses a Shared Dataset to extract a maximum datetime value that I want to use for multiple reports. I have created a shared dataset called MaxSnapshotDateTime.rsd that uses the query:
select max(snapshot_DT) as snapshot_DT from dbo.SystemLog (nolock) where sync= 1
My report dataset Snapshotdatetime uses the shared dataset. And my parameter #snapshotdatetime takes available and default values from the Snapshotdatetime dataset. I want to be able to use this #snapshotdatetime parameter for embedded datasets.
The #snapshotdatetime parameter is the first in the list of parameters. And the Snapshotdatetime dataset is the first in the list of datasets.
When I preview the report in SSDT it displays correctly initially. But once I select View Report the snapshotdatetime parameter displays as a dropdown with "Select a Value" as the default value and my snapshot datetime available in the dropdown.
If I set my available values for the parameter to be None then I get different behaviour: the parameter appears correctly but it is not available for other dataset queries.
Unfortunately I don't have sufficient permissions for a trace. And I have been unable to replicate with another source. Can anyone shed some light on what is happening when View Report is being clicked?
I am taking a wild guess here, but I have faced such issue before and have done lot of head-scratching. Turns out there is a rdl.data file in the solution where the rdl file resides(and it gets created automatically). This is the cache file for the report. When you "Preview" a report, the data and design for the report is fetched from this cache file, not the actual dataset. Hence there are chances it might be stale.
If you really want to see the report's output, instead of previewing it, try running the report from solution. That would be much more reliable.
Hope it helps you.

SSRS - filter existing dataset

I have a report that uses parameters. The default parameters are defaulted to contain all available values, so by default the report the contains all possible data.
I want the user to then be able to deselect some of the values in the parameters, and to refresh the charts in the report, so they can drill down to the data that interests them.
But each time the report is refreshed, it runs the query again, slowing down the process.
Is there a way to allow the user to filter the data in the charts, without re-running the query?
I did find this, but it seems that he also didn't get a solution, or I didn't understand how the solution would work.

To keep the query from running again, two high level steps must happen:
1) Make sure that your filters(parameters) are not included in the query. The query needs to be identical, no matter what the user has selected for a filter. This is done by moving the filters into the report. You can set them up as the filter on the tablix or on the row groups that are displaying the data.
2) Set up caching for the dataset. The easiest way to do this is by pulling the data set out of the report and create a "Shared Dataset." when you upload that to SSRS, define the dataset caching: maybe set it to last an hour. Connect the report to the shared dataset as well.
The full details of this can fill an article, such as http://www.mssqltips.com/sqlservertip/1919/how-to-enable-caching-in-sql-server-reporting-services-ssrs/ (for an old version of SSRS, but these concepts haven't changed much.)

MS reporting services limiting number of rows

I have a report working well where I extract the number of logins per user. Each login takes up one row on the report.
I have date parameters and my DB goes back a year. However it seems the report will only show 40/50 rows despite a report expecting to deliver, say, 250 for the amount of times I logged in.
Is there some setting in reporting services that limits the number of rows delivered. Can't find it anywhere..
Thanks.
The answer to your question: nope, as far as I know there's no real equivalent of SQL's TOP 50 statement in SSRS itself.
Some things that come to mind that may be causing your symptoms / can be investigated:
What happens if you run the query for the dataset in SSMS? Be sure to fill in the exact parameters the report's using (if any).
Run the query as a test from SSRS designer. If you're using Visual Studio: right-click the dataset and hit "Query...", then hit the red exclamation mark and fill in any parameters if needed.
Try putting a CountDistinct call (on your dataset) in a textbox somehwere in the report, by itself.
Check the filtering and grouping on your tablixes, perhaps even by looking at the XML source code for the RDL.
Show the parameters in textboxes (oldskool printf debugging! :D) to make sure they're what you expect them to be when the report's run on the Report Server. If they're not: try deleting the report on the server and re-deploying it.
Have a look at the ExecutionLog2 View in the ReportServer database, specifically the Number of Rows returned.
As mentioned in the comments by Atilla: You may also monitor exact SQL SSRS sends to server using SQL Server Profiler.
