Suppose we have created only one schedule to generate 100 reports.
Once the schedule is subscribed , how the report will be generated ?
Will all 100 reports generated simultaneously ?
or
Reports will be generated sequentially one by one ?
P.S . I am not talking about multiple subscription.I am talking about reports in only one subscription.
I need a little more clarity, are you talking about one subscription running multiple reports or multiple subscriptions?
This isn't really an answer, but I am 4 points too short to comment yet.
This article has some information. Basically it depends how your RS server is set up. Mine is set pretty low. I never see more than one subscription/report running at a time.

For my data driven subscriptions I can see the reports run one at a time during testing.
---update--
MaxActiveReqForOneUser value from rsreportserver.config defines number of report running inparallel . default value is 20
P.S. Subscribed reports run in parallel and maximum report running in parallel are 20 by default.

Can any one of you please help me by providing more details of the column "ExecutionId" in the table "[dbo].[ExecutionLog2]". I thought for each and every report execution from report server it
will create one execution id. However I find one "ExecutionId" has repeated 70 times (Same "ExecutionId") in one of the report server database. So wondering what does it mean/usage of the column "ExecutionId" in the table "[dbo].[ExecutionLog2]"
The internal identifier associated with a request. Requests on the same user sessions share the same execution id.
Sql Server Reporting Services Docs
The ExecutionID field appears to be related to (one or more) executions of a specific report. As long as you are running the same report, the ExecutionId appears not to change, regardless of how many times the report is run, even if the report is run with different parameters and even if the output format is changed (e.g. render on screen, pdf, csv etc.)
As soon as you navigate away from the report, a new ExecutionId will be generated for the next report execution.
I've been trying to get around this issue, and was hoping someone here might have paced the same problem.
My SSRS report has some default parameters that are set dynamically. What is happening is that when a report page is first opened (these reports are running from a custom web app), the 'main' report sproc is fired once, just to grab those 2-3 dynamic parameters, even though no other data from that sproc is displayed at this time (if this seems like overkill, it is...I inherited these reports from a former coworker who designed them). So, since there are 2-3 dynamic parameters, the report was designed to get these default values from a query. So, by the time the report is finally run by the user, the main sproc (just call it "report_getReportData" for simplicity) will have ran about 3-4 times already before it's ever rendered to the page.
What I did was, within the report_getReportData sproc, before doing my select * statement to display all the report data, I created a physical table to hold the 2-3 default values, and I created a new dataset in the report to just run a new sproc that just selects the value from this physical table, nothing else, so the result is the getReportData sproc only fires once, and my new sproc, let's call it 'report_getTwoParameters' fires once for each parameter, but the time cost is negligible since is just does one quick select statement.
This solved the issue of the overall report performance, but since there is now a physical table involved (report_getReportData returns data from a temp table), we face the issue of multiple users not being able to run this report simultaneously. So I guess my post has two questions:
1) Is there even a way to get around the main issue of having the report have to run report_getReportData just to set the 2-3 parameters - like maybe "multicast" the result set returned from the sproc into a couple different datasets or something?
2) If we decide to keep my solution of using the physical table, would anyone have any alternate solutions to this, in order for users to be able to run the report simultaneously but avoid bumping into this same physical table?
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.
I'm currently in the process of creating an extensive Access report (~50 calculated fields) for a client and while I've gotten 99% of the report down, I'm having trouble handling the Sum and Count logic on the report.
In a nutshell, the report is intended to list the attendees at an event, tally up the number of attendees at each track/course, and also list any outstanding dues which will be paid at the door. In addition, and this is where I'm having trouble, the report also shows the revenue from each track/course along with a breakdown of the revenue from commuters vs. people staying overnight.
At the moment, all of the formulas follow fairly similar structures so despite having 50 fields, 99% of those are simply adjusting the fields to fit the relevant variables.
For the report now with revenue, my issue is that although I have the fee data specified in the data tables, Microsoft Access keeps zeroing out the calculations rather than displaying the total on the fly.
Here's two of the formals I'm using:
=((Count([W1]))*[Fee Charged W1])
=Sum([Room & Meals])
Earlier today I think I pinpointed the problem to the fact that Microsoft Access is showing the report essentially per individual rather than displaying one report for the entire dataset. I've confirmed this because I manually checked the data and noticed some fields had null values which explained the null tallies.
My question now is whether there is a way to assign a default value for variables in reports so that the report cancels out any invalid data in the database table? I imagine using VBA would help, but I have little experience in that realm.
Thanks very much in advance for any assistance
Just found the solution which was right under my nose the entire time. I just had to configure the fields to use a Running Sum (also called a Cumulative Total).
The answer came right from a page in the Microsoft Office Website: http://office.microsoft.com/en-us/access-help/summing-in-reports-HA001122444.aspx
I'm tasked with reporting on survey data using Reporting Services 2008.
My challenge is this:
a survey has any number of questions
a question is one of three types (a numerical eval, a yes/no question, or a free text)
To handle this, I decided to use subreports on my main report, e.g. I defined one report for each of the three question types, and now when I'm reporting on a survey, I basically dynamically create a RDL for the survey report, using the three question types as subreports.
That actually works quite nicely so far - but I'm facing one major problem: how do I get the data into the subreports?
The approach I see right now is to have each (sub)report per question type define its own data set, based on a shared data source, to extract the values from the database. I'm pretty sure this would work - but I am not very keen on having potentially 5, 10, 20 subreports going off to the database to get their data independently.
What I was hoping for was being able to go fetch the data once for the whole survey, on the "main" report, and then just feed the appropriate subset of data into each subreport, as its being rendered - but I can't seem to find any way to do this....
Am I missing something totally obvious? I haven't had much exposure to Reporting Services, and my last project with it was four years ago (with Reporting Services 2000) - so there's a good chance I am just blind for the obvious solution :-) Please let me know!
Thanks for any hints, pointers to good articles or blogs on Reporting Services, and any help at all!

The usual way is to pass parameters (like date range) from main report to subreports and then subreports take care of everything else. To improve performance, see if you can render subreports from cache or snapshot. The cache stores report with combination of parameters passed, so after first "database hit" some or most subreports may actually be returned from the cache.
I struggled with the same issue. But there is a way you can achieve reasonable performance using "cached shared dataset". Basically subreports will use larger dataset including all rows for all subreports. By using "dataset filter" each subreport can filter out rows properly.
This is only available for 2008 version however.
If the parameters are the final data you require, then just use them and create a dummy dataset in the subreport - you could just have 'SELECT 1 AS DUMMY' as the sql (this is assuming that the subreports have distinct layouts from one another)
Or perhaps you can rethink the 'master' dataset with a function or table function?
It would still tax the sql server, but at least it would be doing it in one hit and the drain on the RS box would be less.
