passing parameter FROM REPORT TO WINDOWS APP

Hi all. Is it possible to pass parameter FROM Report to my windows application(C#) ? Report is made in Business Intelligence Project. I just want to retrieve the total row number to my windows appication. Is it possible? If yes, Can you provide codes for this? Thanks. Your help would be highly appreciated.

-Ron-

Yes you can pass parameter values from your report to your windows application.

Have a default value for your parameter which is the count of rows of the table and then use Values property of ReportParametersInfo class ro retrieve the value.

Shyam

|||Excluding creative approaches such as exporting the report to HTML and parsing the HTML payload, in general the user has to initiate an action explicitly in the report. Then, assuming you use the Windows Report Viewer, you can sink the event. See the hypelink example in this article.|||

Shyam - I have no idea of what you are saying. Can you provide me sample codes for this? thanks.

Teo Lachev - yes i am using windows report viewer. can't find the hyperlink example in link you gave.

Please Help me....

passing parameter from asp.net application to reporting services report

Hi,

There is a .net application which has a screen with four options(text boxes)

Each of these should take to reports generated by SQL REp Services

This is the requirment

The School selected in the App should be passed on to the report

How should I pass the parameter in my report

so that when user selects a link or text box report for that particular school number is displayed

Thanks

sowree

Are you displaying the report in a report viewer control, or opening up a new browser window with the report URL?

BobP

hi

the report is being viewed using report manager, so the report I have deployed to report server must be displayed when the user selects the menu selecting a school number in the asp app.

I need to know how i pass the parameter in my report rdl 's stored procedure to select the school number selected in the ASP application

Thanks

|||

You would create a parameter in the report rdl to accept the school number, and then use that parameter in the call to the stored proc.

For example: You create a parameter called @.SchoolNumber

exec spgSchoolInfo @.SchooNumber

To pass the parameter to the report in report manager, you would put the school number in the URL: (http://msdn2.microsoft.com/en-US/library/ms153586.aspx)

Example: http://server/reportserver?/Sales/Northwest/Employee Sales Report&rs:Command=Render&SchoolNumber=1234

Passing parameter from a webpage to a report

I am developing a website which need to allow user to pass through several webpages for criteria selection and generate a report base on the selected criteria finally.

Anyone know how to pass the selected value from a webpage to the SQL statement or stored procedure which used to generate the report? Or there are other methods to do so?look at the rendering methods of RS - there's one by URL where you can pass the parameters via URL and request the report.|||I believe you simply build a querystring and append the parameters and values to the end of the querystring.|||Thanks for your kindly reply.

I have another related question see whether anyone can help. Base on my current knowledge, I know that we can pass one value for each parameter. E.g. countryID=20. If I want to pass multiple values for this parameter, e.g. countryID=20, 21, 25, ... How can I do so? Also, how should I set it in report designer for this purpose?|||Can you explain little more in detail (perhaps with some sampoe) ? Is your data in the format 20,21,25 for each record ?|||You could pass in a string like you describe. You would need to have logic in your report or stored procedure to handle such a request, though...|||In my report, there is a chart to compare sales performance between several products which are selected by user. The number of selected products is not fixed. I need to pass multiple productID into the report.

Also, I face a problem that ...seem I can't pass parameters into SQL functions to build dataset. Is it a rule? The error msg is "Syntax error or access violation.". My statement is as follows:

select * from getTable(@.productID)

Notes: getTable is a user-defined function.|||so what u can do

Select * from table where productid in (@.productid)|||In the following statement, getTable is a function with many calculation.

select * from getTable(@.productID)

If I use the one below, I can't get what I want. Also, seem can't be a string e.g. "12, 13, 14"
Select * from table where productid in (@.productid)|||so just pass the value in paenthesis

like '12,13,14'. it will definitely work.

If it is a function. then it should return the value same as u mentioned like "12,13,14"
if u can make it " '12,13,14' " . Then you can pass on values.

Passing paramers in URL to Sharepoint Deep Integrated SSRS Report

I am currently struggling with this one, can anyone help with this supposedly
simple problem.
I am trying to pass report parameters to a Report that exists on A
Sharepoint Site that has had SSRS Deep Intergration applied. Can someone give
me the typical URL to do this, and let me know the parameter settings I need
to set against the RDL.
Reading the msdn stuff suggests it is as simple as adding
¶mname=paramvalue
to the URL that points to the RDL file, but my parameters are being ignored
totally. I have tried playing with the Prompt and default settings of the RDL
file, but whatever I try my URL passed parameter fails. Is there even some
security settings somewhere along the chain that is preventing this query
string interpretation?
This must be something very simple and straight forward for any Sharepoint
SSRS Deep Integration experts out there (are there any of those out there
yet?)
Maybe Microsoft could even assist on this one under the 48 hours response
promise this time?

Steve GHello Steve,
I am sorry that currently our internal application got some error and we
did not get your post. So we did not response at the quick manner.
I would like to know what URL you are using to access the Report.
You could see that when we use the URL to access the erport, we use the
ReportServer.
So you may try to use like this:
http://servername/reportserver?/Sales/YearlySalesSummary&rs:Command=Render&r
s:ShowHideToggle=13¶metername=value
Hope this helps.

Wei Lu

==================================================This posting is provided "AS IS" with no warranties, and confers no rights.|||Wei, I'm having the same problem as the person who started this
thread. The problem is stemming from the fact that in SP2 when you
configure a server for "integrated mode with SharePoint" and not
"native mode", reports (the rdl files) are stored directly in a
SharePoint document library and you can no longer load them using the
"/reportserver?" type syntax for the URL. You have to reference them
in the document library, not on the report server. Now, I've gotten a
parameterless report to render but if an RDL file needs parameters it
ignores any parameters I set in the URL string. The report loads with
this error:
"Report parameter values must be specified before the report can be
displayed. Choose parameter values in the parameters area and click
the Apply button."
which is not true because I did pass them. Here is a sample URL I use:
https://www.mycompany.com/mysite/_layouts/ReportServer/RSViewerPage.aspx?RelativeReportUrl=/mysite/myDocumentLibrary/test.rdl&KeyDate=10/5/2007
This report has only 1 parameter (KeyDate) and it ignores what I pass
in the URL string. PLEASE HELP. I've posted questions about this since
April 07 and nobody has given me a solution yet. I can of course send
parameters to a report using the "Jump To Report" method within the
report designer, but many people like myself prefer to use the "Jump
To URL" method because we can use javascript to launch the drilldown
report in a new window. That's the only reason I don't use "Jump To
Report" since "Jump To Report" always replaces the currently loaded
report with the drilldown report. Very annoying. If the RS development
team would add that feature to let us selectively open a drilldown in
a new window, then this issue would be solved. I've wanted that
feature since RS 2000 and still nothing yet.
Another related problem is that I used to be able to use the Globals
collection such as Globals.ReportName, Globals.ReportServerURL, etc
but they no longer work in SharePoint integrated mode. This is a big
problem too, because I now have to hard code my www.company.com URL in
every drilldown link of every report. That's a big maintainance issue
especially when going from a development to a production server URL.
So far, I'm disappointed with SharePoint integrated mode because of
these shortcomings. SSRS SP2 highly publicized the fantastic
integration with SharePoint, wo-ho! And I adopted and bought into it
and moved our reports to this mode. But these drawbacks are terribly
disappointing. Plus, the reports render much slower because of the 2
server model, but I'm disgressing here...
Does anyone out there using SharePoint mode have answers to these
issues'|||Hello Dave,
According to the product team, this issue maybe the product limitation and
they are still looking for the workaround yet.
Once I got any response, I will update ASAP.

Passing OLAP Parameters Within a URL

Hi there!

My report uses an OLAP query with a (multi-valued) parameter, the MDX generated query is something like "...ON ROWS FROM ( SELECT ( STRTOSET(@.Region, CONSTRAINED) ) ON COLUMNS FROM [cube]) ...".

The report works fine using the Report Manager frontend. Now I want to pass this parameter directly within the query string:

https://servername/ReportServer?/PathTo/MyReport&rs:Command=Render&rs:Format=HTML4.0&Region=[foo].[bar 123].&[baz]

But I cannot get Reporting Services to accept the parameter instead of complaining about a missing parameter value. I've already tried quoting the braces, spaces, and the ampersand, putting the dimension in curly braces and/or quotes... No success.

How do I quote this parameter correctly?

I do this befor but so it was as follow

Report server URL(http://Machinename/reportserver/) + Reports Folder (MyReports/)+Reportname (My report) +"&Firstparametername"+Value+"&secondparametername"+Value

it will be like this

http://Machinename/reportserver/(MyReports/My repor&Firstparametername=Value1&secondparametername=Value

|||

Thanks for your reply.

Normal query parameters work fine, I just can't pass OLAP parameters (dimensions like "[foo].[bar 123].&[baz]") this way. ReportServer won't accept them, I think it doesn't like the way I'm trying to quote them...

Thanks and best regards,
Thomas

Hi Tamer,

I was reading your question and i have the same problem.

Please, tell me, Have you resolved this issue ?

email me to :megch00@.hotmail.com ormanuelgo@.cr-dss.com

Thanks a lot !!

|||

Hi there!

It was indeed quoting related, I must have confused hex with decimal notation in my earlier attempts.

All you have to do is urlencode the parameter names and values. Here is how to quote correctly:

InputEncoded[%5B]%5D&%26spaces+ or%20

Or you let ASP.Net do the job:

1string encodedParam = HttpContext.Current.Server.UrlEncode(myParam);

So ...&Region=[foo].[bar 123].&[baz]... becomes...&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bbaz%5D...

If you want this parameter to have multiple values, just use it multiple times in your URL: ...&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bbaz%5D&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bheureka%5D...

HTH and best regards,
Thomas

passing olap parameters in url

hi. could anyone pls tell me how to pass parameter values on url to an olap
RS 2005 report? i tried to do it as such and got an error.
parameter name is AbsenceTypesAbsenceTypes
parameter value is =[Absence Types].[Absence Types].[Absence Type].&[Absent
Days]
this is the link:
http://localhost/ReportServer/Pages/ReportViewer.aspx?%2fCA_Reports%2fcAtt_01&rs:Command=Render&AbsenceTypesAbsenceTypes=[Absence
Types].[Absence Types].[Absence Type].&[Absent Days]
this is the error:
The path of the item "/CA_Reports/cAtt_01,[Absent Days]" is not valid. The
path must be less than 260 characters long and must not start with slash.
Other restrictions apply.
it's obvious that the & in the value of the parameter is causing this
problem.
also if somebody knows of a site where i can find help on this subject. i've
searched a lot and none talks about the current version of RS with olap.
ThanksURL parameter values always must be encoded. E.g. & needs to be encoded as
%26, [ would be %5B, ] would be %5D.
Lookup the HttpUtility class on MSDN - it provides a static method
HttpUtility.HtmlEncode to perform this encoding.

order by amount desc limit 20.

All i want to do is how to pass the record_id from the main report into the sql command of my subreport to look like this....

Select record_id, distributor_name, customer_id, sum(sales) as amount where record_id =("record_id from main_report") group by record_id, distributor_name, customer_id
order by amount desc limit 20.

My goal is how to view the top 20 accounts per distributor

Thanx a lot!!!1. Make main report
2. make sub report with same parameters.
3. In Design mode of main report, edit->subreport links.

Passing null value parameter to a data-driven subscription

I have a data-driven subscription (DDS) stored procedure that gets called when a subscription fires and returns parameters to a report. One of the parameter values I want to return is NULL, which also happens to be the default value of the corresponding report parameter.

When I set the report parameter to use the default value (NULL) when setting up the subscription in Report Manager, the subscription works fine. When I try to pass the NULL value from the DDS proc to the report, the subscription fails.

I do not know what the error logs say. I've rarely looked at them and what I have seen seems a bit cryptic. I've narrowed down through trial-and-error that passing the NULL value is the issue.

Has anyone else experienced this issue and do you have a resolution?

Thanks in advance for your assistance.

I am having the same issue, please let me know if you have found a resolution.

Thank you,

Dave

|||

I had the same problem. In another thread someone mentioned that there is a problem with null parameters and data-driven subscriptions. It seems like a major bug in reporting services. My workaround was to use something other than null and have the report query recognize this setting as equivalent to null e.g. if it's a varchar field then set to 'NOTHING' and have the report definition query treat 'NOTHING' as NULL. For a uniqueidentifer field I used a guid with all zeroes.

Hope that helps.

Greg

Passing Null to Stored Procedure in Reporting Services

Hello,

I have a report. I need to make a drop-down parameter optional. I've setup the parameter to use a dataset as its source, and I need to allow the value to be null. I've selected allow nulls check box, and I've even tried setting the default value to System.DBNull.Value. But, when the entry is not selected (blank), no data ever comes back. If the data is blank or null, my procedure works (I've tested it). How do I send a null value to the database through reporting services report? I was hoping to avoid creating a special query just for that purpose.

Thanks.

Since you say that it is Blank, the report is passing a blank '', not a null. In your proc, you could have the statement:

if @.Parm = ''

Begin

Select @.Parm = null

End

In your parameter setup, uncheck the Allow Blank, and select the Allow Nulls...

Then, when running the report, when the NULL check box in the parameter panel is checked, a NULL will be passed to the proc.

hth

BobP

|||

Hello,

I have Allow Nulls checked. I do have that safeguard in my procedure. I don't have the option for the null checkbox in the parameter panel though. I am sure I have Allow Nulls checked in my application. How does that get added to the panel?

Thanks.

|||

You might want to consider modifying the stored procedure to default the parameter in question. You can set up the last (or last few) arguments of a stored procedure to be optional by providing a default value for the argument. For example, if you have a stored procedure defined as:

Code Snippet

create dbo.myProc

( @.anArgument varchar(20) = null

)

as

...

Since you have provided a default value to your parameter (as designated in red), you are no longer required to pass this argument to your stored procedure. Sometimes this can help.

Kent

|||

The null check box only gets added when you check the Allow Nulls box.

Also make sure you uncheck the Allow Blanks box.

BobP

|||

Hello,

I have a default value set to null for my stored procedure. I have allow nulls checked. I have allow blanks unchecked. I have verified my stored procedure and it works with nulls and blanks (SP converts blanks to null), and I have run the stored procedure in the RS designer and it works. I am sure of that... But, no matter what, I do not get a nulls checkbox in the parameter area...

Any ideas?

|||

BobP,

I do have Allow Nulls checked, and still it does not show.

Any ideas?

|||What version of SSRS are you using? 2000 or 2005, and which SP?|||

For some reason, SSRS doesn't seem to support "allow NULL" option for drop-down query-based parameters. You are always required to pick one of the parameter values to proceed with the report.

I created a small test report based on an SP that accepts one optional parameter of type INT. I was able to configure optional drop-down parameter for this report by creating a following dataset for parameter query:

Code Snippet

SELECT NULL party_id, '<all customers>' party_name

UNION ALL
SELECT party_id, party_name FROM party ORDER BY party_name

This will add "<all customers>" option to the list of parameters values and return NULL to the SP if this option is selected.

Hope this helps.

Hey,

I was hoping not to have to do that, but your right I believe that is the only option.

passing null reportparameter values

Hi,
Iâ'm using the report viewer object to view a report which works fine until I
need to pass null values. When I use the following code I get â'The
'reportId' parameter is missing a valueâ':
ReportViewer1.ShowParameterPrompts = false;
ReportParameter[] parameters = new ReportParameter[2];
parameters[0] = new ReportParameter("reportId");
parameters[1] = new ReportParameter("userid", "123");
ReportViewer1.ServerReport.SetParameters(parameters);
ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;
ReportViewer1.ServerReport.Refresh();
The reportId is setup for null values, however it still gives me an error:
<ReportParameter Name="reportId">
<DataType>Integer</DataType>
<Nullable>true</Nullable>
<Prompt>reportId</Prompt>
</ReportParameter>
I know other people have had this problem but using â'new
ReportParameter("reportId")â' doesnâ't work for me.
Thanks in advance!I'm guessing here, but do you need to explicitly set the value of the
null parameter. DBNull isn't the same as .Net C# null.

passing null report parameter via a url

Hi,
I have a SP in sql with parameters that can get null values such as:
@.paramguf tinyint=null,
AS
select 1 as kodKibuz,name
from learningstuds
where
(@.paramguf is null or hasamaguf=@.paramguf)
I am sending the report parameters via vb.net
Dim URL As String
URL = "http://localhost/reportserver/reports/tutorials?%2fTutorials%2fKibuzKlita1"
URL += "&rs:Command=render&rc:Parameters=false&rc:Toolbar=false"
URL += "¶mdate=" + Date32.saveDate().ToShortDateString
URL += "¶mguf=" + ddlGuf.SelectedValue
'Pass the URL as a Web request
'Dim request As HttpWebRequest = WebRequest.Create(URL)
Response.Redirect(URL)
How can I send a null value to the report for paramguf?
Thanksquoting KB article http://support.microsoft.com/kb/842853
You can also pass a null value for a parameter to a report by adding
'param:isnull=true' to the URL. For example, if the SalesOrderNumber is a
Null-valued report parameter that must be passed to the report, add the
'SalesOrderNumber:isnull=true' string to the URL."

Passing null parameters via Query-String

I'm trying to call a report, passing my parameters via query-string...
I have one parameter that can receive null values...
Following Books Online, the syntax for null values is :isnull, giving the following sample of URL:
http://exampleWebServerName/reportserver?/foldercontainingreports/orders&division=mailorder®ion=west&sales:isnull
In my report, I shadowed this syntax, it looks like the following:
http://localhost/ReportServer?/ctr_es_reports/entrada_saida&dh_ini=2004-06-01&dh_fim=2004-07-20&func_cd_matricula:isnull
If I pass a common value to func_cd_matricula, like 1 or 2, it works fine, but with this isnull syntax, it gives me the following error:
"The path of the item '/ctr_es_reports/entrada_saida,func_cd_matricula:isnull' is not valid. The full path must be less than 260 characters long, must start with slash; other restrictions apply. Check the documentation for complete set of restrictions."
Does anybody know why this?
Thanks,
Rafa®BOL is incorrect.
Right syntax is
sales:isNull=true

Passing NULL parameter from aspx page to Report Server

Hi,

I was wondering if anyone here could help me out. I have an aspx page that has the ReportViewer control on it. I have a report that has 3 parameters used for a stored procedure. One of the parameter is a datetime parameter and it can be null. For the purposes of this iteration of the report, this parameter needs to be null.

I can not for the life of me figure out how to send over a null parameter from the aspx page. Everything I have tried gives me this error: "The value provided for the report parameter 'StartDate' is not valid for its type. (rsReportParameterTypeMismatch) "

I tried to send the parameter as "&StartDate:isnull", but that did not work. Neither did: "&StartDate=", "&StartDate=NULL", "&StartDate=<NULL>"

I'm reaching my wits end. I can't seem to find any information anywhere about sending a null parameter to ReportServer via the ReportViewer.

Any help would be greatly appreciated.

I can't find out how to pass NULL as the parameter for the report, either. The report server is based in VB, so it uses Nothing instead of Null, but I can't get it to take that, either. I'm not sure how you have the report set up, or what else you are using it for, but it may be easier if you could set NULL as the default value, and then just not pass in the date parameter.

|||

I tried a sample snippet and its working,

ReportParameter rp1 =

newReportParameter("param2",newstring[] {null },false);

Add it to reportviewer control

List<ReportParameter> paramList =newList<ReportParameter>();

paramList.Add(rp2);

ReportViewer1.LocalReport.SetParameters(paramList); //replace local with server report if you are hostin your reports on reporting server

there you go on report side you can check

=IIF( IsNothing(Parameters!param2.Value),"Null value","not nul")

|||

Unfortunately, I can't get the NULL to set for a default parameter in the report either. I tried, setting it equal to:

=NULL
=null
=System.DBNull
=DBNull
=isnull
=:isnull
:isnull
<NULL>
=""
=
just plain leaving it blank

I have noticed that the when going through preview, the checkbox for NULL is checked. But if I run the report, it is not defaulted to a checked state.

It seems like there would be some information about this somewhere. I have a hard time believing that no one has really found this to be an issue before.

Thanks in advance for your help

It looks like sundher_ganesh has come up with a working solution for sending a null value to the report. If you want a default value of null for the report, you can do one of the following:

In the report designer (At least in VS 2005) you can select Null for the default value (It's one of the three radio buttons).

Otherwise, "=Nothing" (without the quotes, of course), works for the default expression.

Yes, he did. I guess we posted around the same time. Thanks so much sundher_ganesh and Benners_J for your help.

Passing non-URL Friendly Parameters?

I have a parameter in my SQL report which is a system account number. This
account number often contains non-URL friendly characters (i.e. '<', '>',
';', ' ' , etc...). How can I create some type of substitition function to
work around this issue?
I reall need to pass the parameter through the URL. Thank you in advance.
- MaxWhat instead of using the GET method, you use the POST method to send your
parameters

Reporting Services should recognize escaped uri parameters. So instead of
'http://Hello World' you can use 'http://Hello%20World'. The same applies to
<, > and so on. The % values are the hex-ascii values, so you might need to
look up an ascii table and do a string replace ( like strUri.Replace(" ",
"%20") )
In .NET 2.0 you should look up for the Uri class and use EscapeUriString or
EscapeDataString.
I hope it's understandable, else you can try it at
http://www.greymana.net/examples/escape.html . For Non-URI friendly
parameters the Dest (param) might be more intersting. It's all in client-side
javascript.

Passing Multivalued Parameters through URL interface

Hi,
We are trying to generate report by passing parameter values through url
In our report, we have a multivalued parameter named "ABC", having values
say, val1, val2 and val3.
When try to generate the report with parameter ABC having values as val1 and
val2 using the url mentioned below, we find that the values are not selected
and report is not rendered.
http://<machinename>/ReportServer/Pages/ReportViewer.aspx?<reportpath>0&rs:Command=Render¶meter=val1,val2
This is working fine for singlevalued parameters.
Thanks in advanced,
Sumit PilankarA comma separated list of values in the QueryString doesn't do it.
I know one way to do it, but it isn't real elegant.
rather than this:
¶m=val1,val2,val3
you do this:
¶m=val1¶m=val2¶m=val3
Andy Potter|||how about UrlEncode(val1,val2,val3)?|||Thank you very much for the suggestion, it worked for me.:)

UrlEncode is required, but we need to form the URL as Andy Potter said.

Parent Report accepts multiple users and based on which it shows the total % of issues submitted by thoses selected users in the multi value list. on drill down i need to send the user list again from the parent so that the child report shows each issue in detail. but when i use Parameters!Users.value i get only the 1st selected value.

could any one pls help me achive this requirement of mine.

Are the data coming from Analysis Services or are they based on a relational data source?

For the relational case I recommend reading the following forum posting: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=163803&SiteID=1

-- Robert

Yes the data in the first report was coming through relational database. and i had given a drill down feature in the first report which takes to the second report which shows the details information off the parameter(multivalued) selected from the first. it worked for me.

I appreciate yr help - Robert

Passing Multivalue Parameters Through a Report Link

I've created a line chart in my report which lists number of transactions by month. I've also created a report to list transactions by day. My goal is for the user to select a month and link the report to the graph with the selected month divided up into days (in other words, the user wants to see the number of transactions for each day in the selected month).

Anyway, everything is working perfectly except for one thing. In the list of parameters that I am passing to the report for each day, I want to pass a multivalue parameter which contains all the transaction IDs the user selected in creating the report (these are supplied by a multivalue parameter). However, in the parameter dialog box where it asks for a value to send to the awaiting parameter, I do not know how to supply more than one value. If I need to pass one value, it will work fine. However, I would like to do something like:

JOIN(Parameters!TransactionID.value, ",")

for the value of TransactionID, but when I generate the report it is not accepting the values. I'm pretty sure its just a format issue, and I just need to know how exactly I should pass these values.

I already understand that when passing multivalue parameters in a URL you need something like:

TransactionID=1&TransactionID=2

...in order to select multiple values. However, this is a slightly different situation. I'm really running out of ideas, so any help would be much appreciated.

Thank you guys so much

can you please paste your select statement, multivalue parameters are automatically rendered if you have something like this in your select

select * from employees where managerid IN(select managerid from managers)

|||

Have you tried:

SELECT *

FROM Managers

WHERE ManagerID in (@.ManagerParm)

This works in Oracle (except for : instead of @.) and I would be surprised if it did not work in SQL server.

NOTE you will not be able to test it using the !, but it it will work for the report.

|||

I'm sorry I wasn't clear. The project I have is in RS 2005 and uses an analysis services data source and the select statement is entirely in MDX. However, the problem really isn't in the select statement. My problem is that I am creating a report link and I want to pass all the values selected in a multivalue parameter to the other report.

If you want to see reproduce the problem, try these steps:

Create a report with a multivalue parameter. Add a textbox. Right-click and select properties. Click the Navigation tab and select "Jump to Report". Select a valid report that accepts a multivalue parameter. Click the parameters button. In the parameter name column, select the multivalue parameter to receive the values. In the parameter value column, I need to pass the values for the current multivalue parameter. This is the problem I am having.

|||

Please read this related thread: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=163803&SiteID=1

It describes the various scenarios of passing multi value parameters to a drillthrough or subreport. In your case, it should be sufficient to just specify =Parameters!ParameterName.Value to pass all values along.

However, note that if the target report contains a parameterized MDX query and you want to use the passed-in parameter values directly in that query, the parameter values in the main report must represent the UniqueNames (not the caption which is usually the parameter label) - otherwise the target MDX query will most likely not work.
