Parameter Value: "Get values from a query" not working on host - reporting-services

I'm having problems when using the option "Get values from a query" in my Parameter settings.
On the server everything works like a charm.
But when I deploy and then launch the report on my hosting, I get an error message:
If I use the option: "None", then everything works fine.
I've placed a test Tablix, to see the result of the dataset on the host, and also this causes no problem.
So the issue is only with the "Get values from a query" section AND only on the hosting.
Anybody got an idea?
EDIT: I turned EnableRemoteErrors on, as requested by the errormessage, but no additional info is given.


The detail of the error is in the SSRS log file located at -->
<SSSRS_INSTALL_DIR>\Report Server\Log Files.
That is where I would go. Based how you describe the dataset driving the parameters works but not when given a value then I would expect this to be a parameter mismatch or missing parameter. Make sure that you are feeding the dataset the parameters you think you are. Also, if you don't allow nulls then make sure you are supplying a default value.


You said, you placed a tablix on the report showing the results of the YearsDOW dataset and this fails. If this also fails when you set your available values to 'None' then we can assume, as the error states, that the issue was with executing the query itself, not your report design.
As this seems to work when you run it from your local machine in development but fails when run from the server I would suspect it's an authentication/permissions issue.
Check the credentials on the datasource in your development environment and compare these to the SSRS server's version of the datasource. Remember, by default datasources do not get overwritten so it maybe that you deployed the datasource initially with one set of credentials then then changed them in your development environment.
If this is the case and the datasource is not used for other reports on the server, then you can either change the project properties to overwrite datasources but personally I prefer to delete the datasource from the server and then redeploy, that way future changes won't affect the servers version unintentionally.
If the datasource is used in other reports without problems then you could just rename the datasource to something unique so it will get redeployed under the new name and your report will point to that new version.

Exported a modified Report from dev to test. Now report complains about missing parameter values

I've updated a report (Data provider based) to include new parameters. The report runs perfectly on the dev environment so I exported it via XPO to the test environment (including all tables and classes). Now when I try to run the report I'm getting a slew of errors stating that parameter X is missing a value.
I know how to fix these. The problem is that one of them is my newly added parameter which I've confirmed via debugging is assigned a value.
Even after multiple:
Forward and CIL compiles
Cache clearings
Re-deploys
Re-imports
Service restarts
the problem persists.
UPDATE: I've tried a Full Build + Full CIL Compile as well. Clearing the XPPIL folder and doing another full build + full cil isn't an option at the moment. So I've gone and set all the parameters to "AllowEmpty" and "Nullable" which does get rid of the error messages. But the core problem persists as I have expected: The parameter I added is not receiving the value from the contract.

SSRS showing wrong data after deploying report

I am having this problem where the data being shown in report is different when I deploy it on server. So let's say if I am viewing report by pressing F5 (to debug) or by clicking on "Preview" button on the report in BI Studio the data shown is correct. But when I deploy the same report and when I run it from server such as http://myserver/reports then data shown is incorrect/missing.
For e.g. in some cases it is not showing data for a particular field and there are some number fields which are showing wrong data. I have cleaned the solution, deleted data cache files, rebuilt and deployed like 100 times but no luck.
When I deploy it shows some warning (which I guess I can ignore) but no errors.
I have checked the database by running queries and stored procedures directly and they all return correct data.
How do I fix this issue?

I went to report server and looked at the XML of one of the data set which was creating problem and found out that the new FIELD I have added is not there. Then I tried to deploy that data set and it said Overwrite Dataset property is set to False and that's why it was not deploying and I missed it in messages when it deploys a solution. So I simply set the property to True, deployed it and viola problem is solved.

SSRS data source connection error

I've just updates a working report where I had to change the location of the database, it should work fine as I've changed it everywhere it needs to be changed I'm sure but I get this when I try run it
The report server cannot process the report. The data source connection information has been deleted. (rsInvalidDataSourceReference)
I've check the data source and it is correct so what could it be?
Thanks.

Fixed it.
The data source was not set to the right value. After changing it (inside the Report properties) everything worked fine.

Issue re-deploying updated default parameters in SSRS report

I have an SSRS (SQL Server 2008 R2) report with several parameters. I'm having an issue where one of the parameters is not consistently choosing its default value when the report is first loaded.
Specifically, it works fine in BIDS but works intermittently (works on one server but not another) once deployed to IIS and viewed in IE. By intermittently, I mean it works on the server I deploy it to, but when I copy the RDS file to another server, the default behaviour for my parameter is broken.
Details
The parameter has a series of specified (constant) integer values specified in the Available Values section, which represent a selection of fixed reporting periods. The Default Values has a single specified value, which matches one of the Available Values.
Options: data type integer, no null values, no multiple values, parameter visible, automatically determine when to refresh.
Any ideas why I'm seeing this behaviour?

That is true, once the report is deployed to the server then the parameters are controlled at the server level.
Once item to note however is if you redeploy the report with changes to the default values THEY WILL NOT be changed on the server!!! The report must be deleted and deployed for the new defaults to take effect.
If you do not wish to delete the report then change the defaults by hand on the Report Server.

I've discovered my own answer to this question. I'm detailing it here for anyone else new-ish to SSRS who might be confused by the same behaviour. The parameters can be managed separately from the RDL file, and defaults can be overridden once the report is deployed to the server. To manage the parameters on the server:
Click on the report name link at top left on the browser page.
Click on the Parameters tab at left.
Manage the parameters as needed (e.g. set the default value).
Click Apply.
Click the report name link (large bold text at top) to return to the report.

Another solution without having to delete the reports (the issue when you delete the report is the logs are also deleted) is to open the new deployed report with ReportBuilder (Modifier dans le Générateur de rapports).
Just save the report and the defaults values will be changed.

lets say your report name is xyz.rdl
if you have set default parameter and deployed it to server now, it will not change on the server.
i suggest 3 options
1. change the parameter 'Has Default' value on the server, by right click manage on the report
2. delete the report on the server and redeploy it
3. deploy a dummy report or old version report with same name say 'xyz.rdl' which doesn't have this parameter, doing this will erase report parameters on the server, report stays in tact. then deploy your new version report with default parameter, now it should work.

I had similar issue. When a report has been deployed to the Server "Without" Default, and you subsequently modify this report in Visual Studio and change the same parameter to have a default, the server will not pickup that the modify report has a default now.
My workaround to this dilemma was to create a dummy parameter and put it to the top of the list. I then redeployed the report with the new dummy parameter and the same modified one with a default parameter. This time the server picked up that the parameter I was interested in as having a default value. I then proceeded to delete the dummy parameter in visual studio and redeployed the report. The parameter that I was interested in remained as having a default value.
I prevented deleting the report and adding subscriptions to it if I had went that route in order to fix my dilemma.

It takes a bit of work to correctly handle all the various scenarios, but it is (at least as of Sql Server 2012) possible to update the parameters from a script by loading the .rdl file as an xml file, and comparing it to the various settings available from the ReportingService2010.GetItemParameters method of the SSRS management web service
Based on that comparison, you can then update the parameters on the SSRS server using the ReportingService2010.SetItemParameters method.
Finally, there is a connect issue "Report parameter defaults not updated during deployment" that is a bit more limited in scope to allow just auto-updating parameter defaults.

I have noticed this is only a problem when making updates to static parameter values (Value "1"). The expression parameter values seem to a good job of getting updated (Value "=iif(1=1, 1, 0)". Screenshot example included below.
I would suggest using an expression. Or if it's a static value just type that in at the manager page. For example:
//ssrsdev/Reports/manage/catalogitem/parameters/Accounts%20Receivables/Bill%20of%20Lading%20Comparison
Also, I typically deploy my reports using the ReportServerTools powershell cmdlet, so I don't know if maybe their deployment does a better job with updating parameters. So you might try installing and deploying with that tool instead of from Visual Studio.

SQL Server Reporting Services Default Values From Query not working in deployed report

In order to populate a textbox in a page header I am setting up a parameter (as you cannot use Fields) and referencing this in the textbox. The parameter has the Default Value set to "From Query" and the Dataset and Value Field are set accordingly. This works a treat in developmentt in Visual Studio 2005. Once I have deployed the report and am viewing the report in the ReportViewer control I get the error:
"Parameter validation failed. It is not possible to provide valid values for all parameters. (rsParameterError)".
If I remove the parameter, the report works fine.
(Strange thing is that I thought I had this working earlier).

You've probably checked, but has the default value copied over? I've had issues in the past with reporting services where the default values were lost when I moved a report from one box to another.

Thanks for the answer - it has pointed me in the right direction...I have been using my own program to deploy multiple reports so rarely look at them via the Report Manager website. Anyway - I just deployed the report on my home PC and it worked fine....looking at the report in Report Manager on both PCs I found that "Prompt User" on the PC that wasn't working was not ticked...go figure. Ticking this resolved the problem.
I am liking the results that I am getting from SSRS, but I am quite new to it and am finding some things (like this) a little frustating...mouse and keyboard are lucky to not find themselves thrown out the window!
