An attempt was made to set a report parameter 'ABC_PrintCopyOriginal_TH' that is not defined in this report

I'm getting the error: "An attempt was made to set a report parameter 'ABC_PrintCopyOriginal_TH"' that is not defined in this report. when I try to view my reports in a web browser. I'm executing this reports through a menu with button code. When the page comes up I get the error.
I have added manually ABC_PrintCopyOriginal_TH in parameter level report design. this ABC_PrintCopyOriginal_TH was enum which I used to print filter expression based on menu item button. eg: when click on original menu button it needs to print original on report design if etc copy button wise versa....
Can you please help me how to resolve this?
Are you using an SSRS Reporting server to host your reports? If so, have you deployed the report and tried restarting the Reporting server after the changes?
What editor are you using to edit the .rdl files?
If deploying and restarting the server doesn't help there is probably a typo in your .rdl file somewhere since you manually add stuff. Try using Report Builder and check if that gives you more info about the issue.

Report Preview not displaying data

Need help on this as I'm quite new to using this Telerik Reporting tool.
I've configured my data source to point to the correct database and I've already set the query to be used to display the report. As you can see below, the data is shown in the preview data source result.
However when I preview it in the report designer, it is not showing any report data as seen below.
I need help on what to do in order to display the records in the report. I'm not sure where to check.
For company/Location you need to send ID=126 not name in preview window, same as in data source query.

SSRS showing old data in Report Server

We have 1 report that's being exported to PDF manually in the web page.
However, when we update a certain value, the new value can be seen in the table but when we tried exporting the data, it keep showing the old value in the report.
The stored procedure used in the report is showing the new value.
It works fine when running the VS 2013.
I am not sure if caching is enabled in our report server but in that RDL file, we did not explicitly specify to cached the data as shown below.
Processing Options Screenshot
Snapshot Options Screenshot
Parameter Settings Screenshot
There are no RDL.Data files in the report server as well and other reports are extracted to PDF and its working fine.
Do you have any idea or did I missed something that needs to be checked?
Thank you.

Automatic update of fields with SSRS

I'm currently working on a Java Project to generate the XML of an SSRS Report, without using Report Builder (this project writes the XML of a report to an .rdl file).
I'm stuck on the Datasets part of my project. I provide a query to my Dataset and when I open my report, my Dataset is created but the fields are not displayed.
And When I execute my report, I have an error that tells me a problem with my DataSet.
This error means "An error occured during local report processing".
The solution I found is to go to "properties of the dataset" and click on "Refresh fields".
"Actualiser les champs" means "Refresh Fields".
The list of fields is displayed and I can run my report without any problem.
So I wanted to know if it was possible to have the fields update automatically without going through the properties of the DataSet and without the action of the user ?
I have already tried to edit the "AutoRefresh" value of the report, without success.
Is there an option to make this happen or some way to run the script behind the button ?
P.S : I need to generate a hundred of Dataset, so my click on "refresh fields" of each Dataset is not viable.
Thank you for any help you can give me.

SSRS report flashes but won't show anything on report server

I have a report to modify on SSRS (just to add a new column for the table that was created using a custom code function). The table was created using natural key and create "case". I added the natural column for the keys and when I previewed it in SSRS, everything looked perfect! However, when I uploaded it to the server, the report can only select partial selections from a drill-down field/widget. If I choose "select all" for the parameters, it flashes then nothing happens (neither an error message nor data is shown).
It was running fine and I was able to select all the selections for the report in Visual Studio and even extract it in Excel. I thought it was a credential problem, so I used my ID and password for the credentials, but it still did not work.
I tried to deploy the original report that was downloaded from the server, but it wasn't working (even without any changes).
Thank you.
