I have the report that I have build with Reporting Services 2008.
In this report, I have a chart that use throught "strip line" an hidden parameter. The hidden parameter is called "AverageRej". The parameter "AverageReg" is populated by a query. This is the situation:
Configuration hidden parameter
In stripLine I have this code:
=iif(IsNothing(Parameters!AverageRejection.Value), 0, Parameters!AverageRejection.Value*100)
But, If I try to show a report and the query not have one or more result I have this error:
The 'AverageRejection' parameter is missing a value
I tried to give a try, I have set AverageRejection as a VisibleParameter, I show a Select box, if I manual setting a null value, I don't have a error message.
What is the error?

Using text only, can't upload any images... (Failed to upload image; an error occurred on the server)
I created a report that works using the cube "Analysis Services Tutorial".
Parameters: City, State-Province.
Table: State Province, City, Internet Sales Count
This report works fine, but when I change the order of parameters to:
State-Province, City
Then I get that error when previewing the report:
An error has occurred during report processing.
The Value expression for the query parameter 'CustomerCity' contains an error: The expression references the parameter 'CustomerCity', which does not exist in the Parameters collection. Letters in the names of parameters must use the correct case.
One solution that I currently see is modifying the content of the rdl-file.
Hope anyone has any other ideas/solutions what I can do...
Ah well only need to change the order of the parameters in the DataSet and with the context menu on right click I can also move the parameter up/down.
as you can see below, i need to pass a parameter value (red arrow)
i tried to use this expression: =iif(Parameters!Country.Count = Parameters!CountryCount.Value, Nothing, Join(Parameters!Country.Value,","))
but im receiving an error when im try to run the report (Error: Subreport could not be shown.)
can you please assist and guide me how to pass multi value parameter?
country - manually list i created (not from DB / SQL)

I am using SSMS 18.5 (fully patched).
I have a report with three (parameter selections; date which is used to select from a list of available items in the second parameter, which in turn is used to make a selection from the 3rd parameter. This report works! When I call it as a subreport from a master report (using the insert subreport), if there IS data found based on the three (03) parameters I pass it, I get the intended results. If no data is found, I receive the "Error: Subreport cannot be shown." Error. THIS IS OK.
My intent is to call this subreport multiple times with different parameters to list out the different result sets.
My question is how do I condition the subreport call in the master report to not show the error message?
Psuedo code for the visibility option:
(IIF(returned value = error message), true, false)
I have tried this directly in the subreport properties (Visibility). I have tried putting the subreport call in a rectangle and I have tried putting it in a table / matrix.
There is NO "field" to reference or rowcount that I am aware of. SSMS only allows reference to items at the same level or higher and not lower (the subreport).
A specific expression ( IIF() ) with an explanation would be appreciated. I have read numerous articles and tried them all with no results.
I created a new report for an overview of a company. I added a report parameter, which default value is determined by query. But if I run the report and this query returns no results, I get the error "Parameter x is missing a value."
I found this post Parameter is missing a value ssrs 2008. But setting the available values to none didn't solved my problem. I allowed empty and null values too.
If I make the parameter visible everything is okay, I can choose a value or not and it works.
My parameter has following settings:
Type: text
Allow empty values: true
Allow null values: true
Allow multiple values: false
Parameter visibility: Hidden
Available values: none
Default values: Get values from a query (this query sometimes has no results)
This appears to be a glitch with SSRS.
From this MSDN blog post:
Force the update of the properties by renaming the parameter
Open the report for editing in Visual Studio.
Expand the Parameters node and rename the affected parameter to ParameterName1.
Set Allow Blank and Nullable to True if not already set.
Deploy the report.
Rename the parameter back to ParameterName.
Deploy the report.
I am having issues with Multi Value Parameter in SSRS Report.
My Parameter contains 10 values. If I Deselect All the values from Parameter I get error that the Parameter cannot be blank so I go back to the drop down and it does not get filled in with the values. I deleted two items from the Parameter and I do not get issues and my list gets populated if I deselect everything.
If i am not wrong, You are saying your parameter drop down gets cleared out once you get the error that "Parameters cannot be blank" ? How about checking "Allow blank" in parameter properties http://msdn.microsoft.com/en-us/library/aa337234(v=SQL.100).aspx ?
Another thing you may like to check is, if there is any non-ascii character in your parameter drop down's available value. Manipulating this parameter values at run time (check/uncheck) could eventually lead to unexpected behaviors like parameters clearing out or report never rendering.
